## Description
I come across a flaky test due to inconsistent error messages from the odbc lib we use for MSSQL database interactions.

```
From above, we got a error message with `\DEL` appended. It is also driving the tests to fail in the CI on random PRs.
We brought this into notice of "fpco", the authors of the library and they got us a [quick fix](https://github.com/fpco/odbc/pull/43), which also improves the errors by removing the redundancy of the error message.
In this PR
- We update the `odbc` library git reference to fc5b592a60
- Update the error messages in tests to conform with improved error messages from `odbc`

**TLDR**: Rename the pytest class names for update mutations by suffixing with `MSSQL` instead of `Mssql`.
We run the pytest in the CI using option `-k "MSSQL or Common"` which runs the test classes having `Common` or `MSSQL` in their name. Assuming the option `-k` to be case insensitive I named the update mutation test classes ending with `Mssql`. To confirm whether the CI is running the update mutation tests, I opened this PR with a commit making a test to fail and it is not reflected in the CI (all tests are passing!). I renamed the test classes with `MSSQL` as suffix. Now, the CI is able to capture the failing test as expected. Finally, the failing test is fixed.

This PR pretty much does the same thing to remote relationship types in schemacache as what #2979 did to remote relationship types in the IR. On main remote relationships are represented by types of form `T from to`. This PR changes it to `T from` which makes it a lot more reusable.

### Description
Tests are not run the same way locally and on CI, which means that tests that work on CI can fail locally. In this case, the setup for each test is creating and dropping a table named `author`; a lot of the tests were also creating a table named `author` in source `pg1`. If `pg1` is the same as the default source, which is the case locally, then all of those tests fail, while the tests that use a default `pg1` such as CI would succeed.
This PR fixes this by renaming `author` to `author_local` where appropriate.

### Description

This PR adds support for adding set-cookie header on the response from the auth webhook. If the set-cookie header is sent by the webhook, it will be forwarded in the graphQL engine response.
Fixes a bug in test-server.sh: testing of get-webhook tests was done by POST method and vice versa. To fix, the parameters were swapped.

Please refer to the docs to see how to send the set-cookie header from webhook.
### Limitations, known bugs & workarounds
>
- Support for only set-cookie header forwarding is added
- the value forwarded in the set-cookie header cannot be validated completely, the [Cookie](https://hackage.haskell.org/package/cookie) package has been used to parse the header value and any unnecessary information is stripped off before forwarding the header. The standard given in [RFC6265](https://datatracker.ietf.org/doc/html/rfc6265) has been followed for the Set-Cookie format.

## Description
<!-- Please fill thier. -->
<!-- Describe the changes from a user's perspective -->
We don't have dependency reporting mechanism for `mssql_run_sql` API i.e when a database object (table, column etc.) is dropped through the API we should raise an exception if any dependencies (relationships, permissions etc.) with the database object exists in the metadata.
This PR addresses the above mentioned problem by
-> Integrating transaction to the API to rollback the SQL query execution if dependencies exists and exception is thrown
-> Accepting `cascade` optional field in the API payload to drop the dependencies, if any
-> Accepting `check_metadata_consistency` optional field to bypass (if value set to `false`) the dependency check
### Related Issues
<!-- Please make surt title -->
<!-- Add the issue number below (e.g. #234) -->

### Solution and Design
<!-- How is this iss -->
<!-- It's better if we elaborate -->
The design/solution follows the `run_sql` API implementation for Postgres backend.
### Steps to test and verify
<!-- If this is a fehis is a bug-fix, how do we verify the fix? -->
- Create author - article tables and track them
- Defined object and array relationships
- Try to drop the article table without cascade or cascade set to `false`
- The server should raise the relationship dependency exists exception

While it looks like a lot of work in FromIr.hs, you can rather review the type changes in `Hasura.Backends.MySQL.Types.Internal` and the changes to FromIr are only to reflect that. Essentially we're simplifying the FromIr code to not think about SQL-based joins: instead, FromIr produces fields necessary for the dataloader Plan/Execute to do their job properly.
I've done my best to ensure that all the hunks in the diff in this PR are minimal for slightly easier perusing.
I think future PRs will be more intentionally well structured, rather than created retroactively.
**Preceding PR:** #2549
**Next PR**: #2367
The tests have been run like this on my machine. I don't know more beyond that.

Prior to this change, the SQL expression that resulted from translating permissions on functions would refer to the table of the function's return type, rather than the set of rows selected from the function being called.
Now the SQL that results from translating permissions correctly refer to the selected rows.
This PR also contains the suggested additions of https://github.com/hasura/graphql-engine-mono/pull/2563#discussion_r726116863, which simplifies the Boolean Expression IR, but in turn makes the Schema Dependency Discovery algorithm work a bit harder.
We are changing the definition of `data OpExpG`, but the format accepted by its JSON parser remains unchanged. While there does exist a generically derived `instance ToJSON OpExpG` this is only used in the (unpublished) `/v1/metadata/dump_internal_state` API.

This PR improves error messages in our metadata API by displaying a message with the name of the failing command and a link to our documentation. Furthermore, it harmonizes our internal uses of `withObject`, to respect the convention of using the Haskell type name, now that the Aeson error message is displayed as an "internal error message".

While adding [insert mutation schema parser for MSSQL backend](https://github.com/hasura/graphql-engine-mono/pull/2141) I also included [identity](https://en.wikipedia.org/wiki/Identity_column) notion to table columns across all backends. In MSSQL we cannot insert any value (even `DEFAULT` expression) into Identity columns. This behavior of identity columns is not same in Postgres as we can insert values. This PR drops the notion of identity in the column info. The context of identity columns for MSSQL is carried in `ExtraTableMetadata` type.

### Description
We always build a subscription root, even when there was no possible fields. This breaks some third party clients, as the spec does not allow empty types in the schema. This PR fixes this by changing the `buildSubscriptionParser` helper to return a `Maybe` value, and harmonizes / cleans places where we build the subscription root.

### Description
The inherited roles integration tests were behind a flag, and its corresponding fixture, presumably to avoid enabling the option globally. However, #2288 introduced a new test using inherited roles that was not gated behind the flag, which fails when run with `dev.sh`. However, that test works on CI... because inherited roles are globally enabled there.
Consequently, this PR:
- globally enables inherited roles in dev.sh
- removes the flag and the associated fixture

### Description
During the PDV refactor that led to 2.0, we broke an undocumented and untested semantic of inserts: accepting _explicit_ null values in nested object inserts.
In short: in the schema, we often distinguish between _explicit_ null values `{id: 3, author: null}` and _implicit_ null values that correspond to the field being omitted `{id: 3}`. In this particular case, we forgot to accept explicit null values. Since the field is optional (meaning we accept implicit null values), it was nullable in the schema, like it was in pre-PDV times. But in practice we would reject explicit nulls.
This PR fixes this, and adds a test. Furthermore, it does a bit of a cleanup of the Mutation part of the schema, and more specifically of all insertion code.

### Description
Our python test suite has several major problems; one of them being that the tests themselves are not responsible for their own setup. We are therefore using environment variables for all matters of configuration, such as _where the postgres instance is_. This is something that should be changed, but in the meantime, it is the test implementer's responsibility to ensure that tests have a consistent setup in CI and locally, or to to add the proper "skip" annotations.
The recently added `test_pg_add_source_with_source_parameters` fails to do so: as it tests adding a postgres source from hardcoded parameters, rather than relying on environment variables, it only works if the postgres instance is at the matching address, which happens to be the one set in the circle ci config. This is undesirable for two reasons:
- it breaks local tests: running tests locally with `dev.sh` sets postgres up differently, and the test fails;
- a change to the circle config would result in failures in that test.
Sadly, there's no good solution here: our tests do not currently support expanding environment variables in the queries' yaml files, meaning it's not possible to set the values of all those parameters differently in each environment. And we haven't yet started working towards having a unified testing environment setup.
As a result, this PR disables the offending test UNLESS the postgres instance happens to be exactly where the test expects it. This is also very inelegant and adds more tech debt to the pile, but I do not see how to fix this with our current test infrastructure. :(

The materialized views cannot be mutated, so this commit removes the option to run mutation on the materialized views via graphql endpoint. Before this, users could have tried running mutation for the materialized views using the graphql endpoint (or from HGE console), which would have resulted in the following error:
``` JSON
{
"errors": [
{
"extensions": {
"internal": {
"statement": "WITH \"articles_mat_view__mutation_result_alias\" AS (DELETE FROM \"public\".\"articles_mat_view\" WHERE (('true') AND (((((\"public\".\"articles_mat_view\".\"id\") = (('20155721-961c-4d8b-a5c4-873ed62c7a61')::uuid)) AND ('true')) AND ('true')) AND ('true'))) RETURNING * ), \"articles_mat_view__all_columns_alias\" AS (SELECT \"id\" , \"author_id\" , \"content\" , \"test_col\" , \"test_col2\" FROM \"articles_mat_view__mutation_result_alias\" ) SELECT json_build_object('affected_rows', (SELECT COUNT(*) FROM \"articles_mat_view__all_columns_alias\" ) ) ",

"description": null
},
"arguments": []

"path": "$",

}
```
So, we don't want to generate the mutation fields for the materialized views altogether.

GitOrigin-RevId: 4ef441764035a8039e1c780d454569ee1f2febc3
When adding object relationships, we set the nullability of the generated GraphQL field based on whether the database backend enforces that the referenced data always exists. For manual relationships (corresponding to `manual_configuration`), the database backend is unaware of any relationship between data, and hence such fields are always set to be nullable.
For relationships generated from foreign key constraints (corresponding to `foreign_key_constraint_on`), we distinguish between two cases:
1. The "forward" object relationship from a referencing table (i.e. which has the foreign key constraint) to a referenced table. This should be set to be non-nullable when all referencing columns are non-nullable. But in fact, it used to set it to be non-nullable if *any* referencing column is non-nullable, which is only correct in Postgres when `MATCH FULL` is set (a flag we don't consider). This fixes that by changing a boolean conjunction to a disjunction.
2. The "reverse" object relationship from a referenced table to a referencing table which has the foreign key constraint. This should always be set to be nullable. But in fact, it used to always be set to non-nullable, as was reported in hasura/graphql-engine#7201. This fixes that.
Moreover, we have moved the computation of the nullability from `Hasura.RQL.DDL.Relationship` to `Hasura.GraphQL.Schema.Select`: this nullability used to be passed through the `riIsNullable` field of `RelInfo`, but for array relationships this information is not actually used, and moreover the remaining fields of `RelInfo` are already enough to deduce the nullability.
This also adds regression tests for both (1) and (2) above.

In hasura/graphql-engine#7172, an issue was found where under certain conditions a JSON field from Postgres would be parsed as a GraphQL input object, which is not possible in general, and also unnecessary. Luckily, this was already fixed by the time `v2.0.6` got around, presumably thanks to 4a83bb1834. This adds a regression test.

This removes the file `bahnql_query.yaml`, which is no longer being used.
a509a86eaa (hasura/graphql-engine#1117) changed the way we test the remote schema feature from using external GraphQL services to running our own mini GraphQL server for testing purposes. This gives us a lot of in-codebase flexibility on the behavior of "remote" GraphQL servers.
During this work, the `bahnql_query.yaml` test was swapped out for the `simple2_query.yaml` test. The former essentially tests if a field from a remote schema can be fetched, whereas the latter tests whether an entry can be fetched from the (non-remote!) database.
It's not clear to me why `bahnql_query.yaml` was no longer used. In any case, the relevant setup code was removed, and this test can no longer be run. Presumably we test such basic functionality already in many other ways.

### Solution and Design

Prior to this change, we apply `LIMIT` and `OFFSET` to the outer selection from sub-query which includes joins for relationships. Now, we move `LIMIT` and `OFFSET` (if present) to inner selection of base table. But, this isn't done always! If there are order by relationships' columns we apply at the outer selection.

### Description
>
From HGE version 2.0 onwards, all remote relationship fields are generated as plain types without non-nullable and lists. This PR fixes the same.
### Changelog
- [x] `CHANGELOG.md` is updated with user-facing content relevant to this PR. If no changelog is required, then add the `no-changelog-required` label.
### Affected components
- [x] Server
- [x] Tests
### Related Issues
->
fix https://github.com/hasura/graphql-engine/issues/7284
### Steps to test and verify
>
- Create a remote relationship to a field in remote schema with non-nullable or list type
- The HGE introspection should give the remote relationship field type correctly as like in the remote schema

During the "generalization" of the code, we removed the [generated instances](9d63187803 (diff-7b8382ab20e441fa214586be491eb6f7ca904d8b20ed97894c16a339be45219aL72)) of `Eq` and `Hashable` in favour of manually written ones, because for a time we were struggling with `AnyBackend`.
In the process, we lost one constructor, `MOEndpoint`. It's unlikely to have ever been an issue, since duplicate endpoints are unlikely, but it is nonetheless wrong.
This PR simply goes back to default derived instances, now that we can, fixing the problem and making the code simpler.
---
However, after filing this PR, I realized **it broke rest endpoint tests**. Upon closer inspection, it turns out that while we had proper checks in place, because of this bug we were actually failing _differently_ during metadata checks. This PR actually improves error messages for invalid endpoint configurations?! 🙀
This is a tiny bit scary. ^^'

I finally got fed up trying to decipher the messages from failing assertions in integration tests and was thus spurred into action :-)
Instead of using the `repr(..)` format for the `OrderedDict`s of query responses we now deliberately format them as JSON with indentation.

Blocked on https://github.com/hasura/graphql-engine-mono/pull/1640.
While fiddling with BigQuery I noticed a severe issue with offset/limit for array-aggregates. I've fixed it now.
The basic problem was that I was using a query like this:
```graphql
query MyQuery {
hasura_Artist(order_by: {artist_self_id: asc}) {
artist_self_id
albums_aggregate(order_by: {album_self_id: asc}, limit: 2) {
nodes {
album_self_id
}
aggregate {
count
}
}
}
}
```
Producing this SQL:
```sql
SELECT `t_Artist1`.`artist_self_id` AS `artist_self_id`,
STRUCT(IFNULL(`aa_albums1`.`nodes`, NULL) AS `nodes`, IFNULL(`aa_albums1`.`aggregate`, STRUCT(0 AS `count`)) AS `aggregate`) AS `albums_aggregate`
FROM `hasura`.`Artist` AS `t_Artist1`
LEFT OUTER JOIN (SELECT ARRAY_AGG(STRUCT(`t_Album1`.`album_self_id` AS `album_self_id`) ORDER BY (`t_Album1`.`album_self_id`) ASC) AS `nodes`,
STRUCT(COUNT(*) AS `count`) AS `aggregate`,
`t_Album1`.`artist_other_id` AS `artist_other_id`
FROM (SELECT *
FROM `hasura`.`Album` AS `t_Album1`
ORDER BY (`t_Album1`.`album_self_id`) ASC NULLS FIRST
-- PROBLEM HERE
LIMIT @param0) AS `t_Album1`
GROUP BY `t_Album1`.`artist_other_id`)
AS `aa_albums1`
ON (`aa_albums1`.`artist_other_id` = `t_Artist1`.`artist_self_id`)
ORDER BY (`t_Artist1`.`artist_self_id`) ASC NULLS FIRST
```
Note the `LIMIT @param0` -- that is incorrect because we want to limit
per artist. Instead, we want:
```sql
SELECT `t_Artist1`.`artist_self_id` AS `artist_self_id`,
STRUCT(IFNULL(`aa_albums1`.`nodes`, NULL) AS `nodes`, IFNULL(`aa_albums1`.`aggregate`, STRUCT(0 AS `count`)) AS `aggregate`) AS `albums_aggregate`
FROM `hasura`.`Artist` AS `t_Artist1`
LEFT OUTER JOIN (SELECT ARRAY_AGG(STRUCT(`t_Album1`.`album_self_id` AS `album_self_id`) ORDER BY (`t_Album1`.`album_self_id`) ASC) AS `nodes`,
STRUCT(COUNT(*) AS `count`) AS `aggregate`,
`t_Album1`.`artist_other_id` AS `artist_other_id`
FROM (SELECT *,
-- ADDED
ROW_NUMBER() OVER(PARTITION BY artist_other_id) artist_album_index
FROM `hasura`.`Album` AS `t_Album1`
ORDER BY (`t_Album1`.`album_self_id`) ASC NULLS FIRST
) AS `t_Album1`
-- CHANGED
WHERE artist_album_index <= @param
GROUP BY `t_Album1`.`artist_other_id`)
AS `aa_albums1`
ON (`aa_albums1`.`artist_other_id` = `t_Artist1`.`artist_self_id`)
ORDER BY (`t_Artist1`.`artist_self_id`) ASC NULLS FIRST
```
That serves both the LIMIT/OFFSET function in the where clause. Then,
both the ARRAY_AGG and the COUNT are correct per artist.
I've updated my Haskell test suite to add regression tests for this. I'll push a commit for Python tests shortly. The tests still pass there.
This just fixes a case that we hadn't noticed.

A pull request for cleaning up small issues, bugs, redundancies and missing things in the BigQuery backend.
Summary:
1. Remove duplicate projection fields - BigQuery rejects these.
2. Add order_by to the test suite cases, as it was returning inconsistent results.
3. Add lots of in FromIr about how the dataloader approach is given support.
4. Produce the correct output structure for aggregates:
a. Should be a singleton object for a top-level aggregate query.
b. Should have appropriate aggregate{} and nodes{} labels.
c. **Support for nodes** (via array_agg).
5. Smooth over support of array aggregates by removing the fields used for joining with an explicit projection of each wanted field.

Remote relationships are now supported on SQL Server and BigQuery. The major change though is the re-architecture of remote join execution logic. Prior to this PR, each backend is responsible for processing the remote relationships that are part of their AST.
This is not ideal as there is nothing specific about a remote join's execution that ties it to a backend. The only backend specific part is whether or not the specification of the remote relationship is valid (i.e, we'll need to validate whether the scalars are compatible).
The approach now changes to this:
1. Before delegating the AST to the backend, we traverse the AST, collect all the remote joins while modifying the AST to add necessary join fields where needed.
1. Once the remote joins are collected from the AST, the database call is made to fetch the response. The necessary data for the remote join(s) is collected from the database's response and one or more remote schema calls are constructed as necessary.
1. The remote schema calls are then executed and the data from the database and from the remote schemas is joined to produce the final response.
### Known issues
1. Ideally the traversal of the IR to collect remote joins should return an AST which does not include remote join fields. This operation can be type safe but isn't taken up as part of the PR.
1. There is a lot of code duplication between `Transport/HTTP.hs` and `Transport/Websocket.hs` which needs to be fixed ASAP. This too hasn't been taken up by this PR.
1. The type which represents the execution plan is only modified to handle our current remote joins and as such it will have to be changed to accommodate general remote joins.
1. Use of lenses would have reduced the boilerplate code to collect remote joins from the base AST.
1. The current remote join logic assumes that the join columns of a remote relationship appear with their names in the database response. This however is incorrect as they could be aliased. This can be taken up by anyone, I've left a comment in the code.
### Notes to the reviewers
I think it is best reviewed commit by commit.
1. The first one is very straight forward.
1. The second one refactors the remote join execution logic but other than moving things around, it doesn't change the user facing functionality. This moves Postgres specific parts to `Backends/Postgres` module from `Execute`. Some IR related code to `Hasura.RQL.IR` module. Simplifies various type class function signatures as a backend doesn't have to handle remote joins anymore
1. The third one fixes partial case matches that for some weird reason weren't shown as warnings before this refactor
1. The fourth one generalizes the validation logic of remote relationships and implements `scalarTypeGraphQLName` function on SQL Server and BigQuery which is used by the validation logic. This enables remote relationships on BigQuery and SQL Server.

This reverts the remote schema type customisation and namespacing feature temporarily as we test for certain conditions.
