Is there a quick way to reset a PgSQL cluster to its pristine
state--i.e., to what initdb gives but preserving configuration
customizations?
Not that I am aware of.
If you describe your use-case then meaningful suggestions could be
offered.
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.
use a file system, like zfs, that supports snapshots. initdb the
first time, configure your system, then snapshot it. each successive
time, stop postgres, revert the snapshot, restart postgres.
