Hey list,
I have a cron script that runs a couple cleanup commands on my
database. It runs three commands:
VACUUM ANALYZE;
CLUSTER;
REINDEX DATABASE "database";
They are run in the above order. I was wondering if there's a better
order to do this in. For example, should the ANALYZE be run _after_
the CLUSTER? Does that affect the query planner? And the same goes for
REINDEX.
I could always split up the VACUUM and ANALYZE into separate commands
as well, if order would have any effect.
I _do_ have autovacuum running. However, I like to run these commands
during a low-traffic time just so autovacuum slows the site down as
least as possible during high-load times.
Thanks!
