Currently we're just running the automated parser tests on commit on the MySQL backend; because the PostgreSQL and SQLite backends are less well tested by developers, they're ideal candidates for additional automated testing.
Running parser tests under those infrastructures will provide at least some minimal confirmation that basic operations work (update, create articles, read templates) until other full-functionality tests are available.
Of course this is assuming the parser test suite actually runs under them yet... ;)
