Sorry, I forgot to mention: autovacuum was enabled and I also ran
this script every night via cron:
#!/bin/bash
FULL=''
test $(date +%w) -eq 0 && FULL='FULL'
exec psql -U dbm -c "VACUUM ${FULL} VERBOSE ANALYZE" dbm
The app at least felt faster with the daily vacuum, even though
autovacuum was running. I don't have a good explanation for that,
either.
Autovacuum by default won't do enough work for many production
databases. You still have to configure it.
