Most of the time autovacuum is fine and can handle all your vacuuming
and analyzing needs no problem.
However, on some very heavy traffic or large sized databases you may
need to tune it so that it keeps up with your needs.
On my production database servers I had to adjust a few settings to
make autovac more aggressive so that it wasn't falling behind. On all
my other pg instances the default settings are just fine.
