Hi

How long is a piece of string?

While we're at it, how often do I vacuum analyze?

Seriously though, how do I try measure this?

Is autovacuum not going to work for your case?

A

1: Turn on autovacuum.
2: Look up the thread on nagios plugins for pgsql and rip the query
for checking bloat out of it, or alternatively, use NAGIOS I guess. :)

monitor your db for bloat, and if autovacuum isn't keeping up either
set it to be more aggresive, or schedule manual vacuums for the tables
that need it.
