Having lots of tests is a good thing. Bring 'em on.

If you use SQLite for that, then it all runs in a single thread and it
could easily take 30 minutes or longer.

Now all you have to do is parallelise the tests and everything can
work 10 times quicker and it would be much faster than the time SQLite
produced.

So using PostgreSQL for testing would be both quicker and more
accurate, if you set the tests up right.

The PostgreSQL regression tests are parallelised - if they weren't
we'd produce a lot less work
