Might as well dupe the old text; this went out to the performance list:
Greg Sabino Mullane released a Nagios plug-in for PostgreSQL that you can
grab at http://bucardo.org/nagios_postgres/ , and while that is itself
nice the thing I found most remarkable is the bloat check. The majority of
that code is an impressive bit of SQL that anyone could use even if you
have no interest in Nagios, which is why I point it out for broader
attention. Look in check_postgres.pl for the "check_bloat" routine and the
big statement starting at the aptly labled "This was fun to write"
section. If you pull that out of there and replace $MINPAGES and
$MINIPAGES near the end with real values, you can pop that into a
standalone query and execute it directly.
That's what gives the summary Jeremy included in his message.
