You are correct, it is 7.4 we are running on a RHEL3 system.
The database itself is vacuumed via cron 6 times a day.

The other thing you need to watch out for is that your FSM setting is
large enough to recover all of the dead space. If your vacuum runs aren't
recovering as much dead space as is being created on average, then you are
going to have dead space accumalate.

match
