All tests should run on the CI

[osaxma]

This is just a reminder for the next major release.

There are multiple tests that require specific setup for the postgres container and some cannot share the same container with other tests:

• non-ascii connection strings tests character (see tests added in add non-ascii connection string tests #63)
• logical replication tests (see notes in Fix an issue with logical replication test and simplify the test #61)
• Connection lifecycle tests (see connection_test.dart).

If running multiple containers is the way to go, then any conflicts in port numbers and container names should be taken into account as these tests may run concurrently.
