I'm using PostgreSQL 7.4.2, and I'm having a little issue with rules.
I created a rule to watch for any inserts to table XYZ, and registered
a listener. But as I simply do a select on the table, I receive several
notifications when nothing has been inserted into the table.

Does pg_ctl status return true even if the database is not ready yet to
receive requests? We are using pg_ctl status to tell us if the database
is up, but I'm wondering if it could return true, but a client could
connect and still get the "FATAL: database is starting up" error?

Jeff, are you doing CLUSTER operations too?
Some preliminary testing says that:

CLUSTER leaks a pg_temp_nnn relcache entry per call; if table

pg_ctl status just checks that the postmaster process is present.
