Alpine is often slower than Debian (because musl is sometimes slower than glibc) and not how anyone actually deploys PostgreSQL in production.
Most notably, some floating-point computations result in slightly different values, and Debian ships with better support for different locales so sorting text (e.g. with `ORDER BY`) behaves differently.
Let's test against an environment that people are likely to actually use.
As a result, there are slight changes to the results of PostGIS computations in a couple of test cases.

This changes our test configuration to use the PostgreSQL 16 image from `postgis/postgis`.
In addition, it bumps PostGIS to v3.4 (from v3.3).

Instead, we update the metadata to point to the correct database URL each time we start HGE.
This means we can run the tests on macOS (and any other environment where Docker runs inside a VM).
I was hoping this would solve the issues we're seeing on CI too, but no such luck.

These tests ensure that upgrading HGE preserves the GraphQL schema.
They do this by running two different versions of HGE against the same metadata, and ensuring that the GraphQL schema doesn't change.
We might find that in the future, we make an additive change that makes these tests fail. Improving the tests to allow for this is left as an exercise to whoever triggers it. (Sorry.)
Currently, we do this with:
* an empty database (zero tracked relations)
* the Chinook dataset
* the "huge schema" dataset
The base version of HGE tested against can be overridden with an option. The version must be available on Docker Hub.
Further information is in the Haddock documentation.
