I wanted to get ahead of the problem, hence my question here. :) I've set this to run at night ('iwt' being the DB in question):

su postgres -c "psql iwt -c \"VACUUM ANALYZE VERBOSE\"

And why not the vacuumdb command?:

su postgres -c "vacuumdb --analyze --verbose iwt"


But this is duct-tape and bailing-wire. You REALLY need to make sure that autovacuum is running - you are likely to have much better results with less pain.

Cheers,

As for why '-c ...', I guess it was just a matter of which command came to mind first. :) Is there a particular benefit to using the 'vacuumdb' wrapper?

As for autovacuum, I assumed (yes, I know) that all v8.x releases enabled it by default. How would I confirm that it's running or not?
