This is a sample Vue.js app with Auth0 integration. Has a simple schema with users and article tables with permissions setup. Once the user logs in to the app, the articles written by the user would be shown.
The word "reset" is little ambiguous (reset to scratch or reset to last known consistent state). metadata reset clears the all the metadata to mimic a freshly installed hasura instance. This actually invokes the clear_metadata API in the backend and hence should also be called metadata clear for perfect clarity.
All references to metadata reset should be changed to metadata clear.

### Description
<!-- The title might not be enough to convey how this change affects the user. -->
<!-- Describe the changes from a user's perspective -->
This PR adds a bash script and a serverless function to clean up the output of `pg_dump` so that it can be used as a migration file for Hasura. This can be later integrated with the CLI so that the cleanup is handled by CLI.

### Solution and Design
<!-- How is this issue solved/fixed? What is the design? -->
<!-- It's better if we elaborate -->
- A serverless function written in Go gets the SQL content though HTTP POST.
- A set of pre-defined lines are removed from this SQL string.
- SQL comments are removed using regex matching.
- Postgres triggers created by Hasura for use with event triggers are removed with regex matching.
- Empty newlines are removed by regex matching.
- Resulting string is returned in the HTTP response.
### Steps to test and verify
<!-- If this is a feature, what are the steps to try them out? -->
<!-- If this is a bug-fix, how do we verify the fix? -->
```bash
curl --data-binary @filename.sql https://hasura-edit-pg-dump.now.sh > newfile.sql

From `alpha-40` we've been using a `WHERE` clause to fetch required rows and generate mutation response. This has a few limitations like the requirement of a primary key/unique constraint. This also returns inconsistent data on `delete` mutation as mentioned in #1794.
Now, we're using `VALUES (..)` (refer [here](https://www.postgresql.org/docs/current/sql-values.html)) expression to form virtual table rows in `SQL` to generate mutation response.
Internal changes:-
- Not to use primary key/unique constraint columns:-
- Revert back to `ConstraintName` from `TableConstraint` in `TableInfo` type
- Remove `tcCols` field in `TableConstraint` type
- Modify `table_info.sql` and `fetchTableMeta` function `SQL`
- A test case to perform `delete` mutation and returning relational objects.
This is a forked version of Urigo's [WhatsApp Clone](https://github.com/Urigo/WhatsApp-Clone-server), integrated with Hasura.
Hasura GraphQL APIs are used in place of custom resolvers. A simple JWT server replaces the original auth server. Image uploads use the same Cloudinary APIs.
[Original React Client](https://github.com/Urigo/WhatsApp-Clone-Client-React) has been updated to match Hasura APIs and typescript definitions have been generated using GraphQL Code Generator.
There was a postgres permission issue in the docs. The hasura user
needed to be owner of the system schemas (hdb_catalog), otherwise it
won't be able to table schema changes during version upgrades.
