Fixes#3660. Load the config after getting the pg version but before loading the schema.
The regression happened on f09655b.
Also remove schema cache load wrapper and separate db queries in different functions.

Fixes https://github.com/PostgREST/postgrest/issues/3523.
Now if there's a failure when obtaining the pg version OR schema cache,
we do the same retrying process. This way we don't add two retries.
Refactors and renames the "connectionWorker" to "schemaCacheLoader".
This makes more sense since what we really want is the schema cache,
the version is the pre-requisite for ensuring our
schema cache queries work.
Additionally, we no longer log ` Attempting to connect to the database...`
at startup unnecessarily. This is only logged whenever there's a retry attempt.
It's very unlikely, but it can (and did) happen that both the server and
admin ports have the same number returned from freeport(). This then
leads to a situation where PostgREST will accept the same port in both
cases, because the host "localhost" will allow binding to ipv4 or ipv6
respectively. This will make the IO tests fail.
This change makes sure that the admin port will never be the same as the
server port and thus avoids this problem.
The $subject commit broke internal_schema_cache_sleep for other tests.
This reverts the order change, but keeps the scaling by x1000 to ms and
thus changes other users of this setting to the new scale.
By increasing the delays in this test by factor 400x, postgrest will not
swamp pg with connection retries after the failed schema cache anymore.
This would happen because there is no backoff included after fatal
errors. Once it does, the io tests hang indefinitely in CI.
The statement timeout needs to be cleaned up after each test that
modifies it instead of before the test. Otherwise the changed timeout
leaks into other tests.
* new --replica option to `postgrest-with-postgresql-*`
* new command `postgrest-test-replica`
* new sanity tests on test_replica.py
* add postgrest-test-replica to postgrest-check and postgrest-coverage
f9ee1f7e introduced the hoisting of function settings as transaction-scoped
settings. However, this currently doesn't work with memory units, which are
case-sensitive according to the docs [1]. This removes the lowercasing of
values to make them work.
This is not added to the CHANGELOG, because this feature was not released, yet.

With this:
- Is no longer necessary to pass observer as an argument
to every function that needs observations.
- We can invoke the observer on every function that uses AppConfig.
However it'd be better to just call the observer in the upper modules
(like on App.hs).
