We have a lot of code that tests interaction with a PgSQL cluster on the
same server that has a live production cluster. To keep the testing
environment separate from production, we create a PgSQL cluster in a
temp directory then run tests against that.
This, as you can imagine, is pretty expensive to set up each time …
initdb is not fast! It would be nice if we could just create a single
test PgSQL cluster then wipe it clean at the end of each test.
