You may find what you are looking for with Bruce Momjian's pgmonitor
tool.

Alternatively, you could just use a simple shell script. All of the
Postgres connections are separate jobs with the identifier "postgres:"
at the begining. So you could simply do:

ps ax | grep postgres:

on a RH Linux machine.

With some sed/awk commands, you could sort the job information even
finer. For example, to find out which users are logged onto the
database at any given time:

ps ax | grep postgres: | awk '{print $6 | "sort" } ' | uniq

I'm sure if you fooled around with this, you could come up with
something tailored to your needs in no time.
