pg_stat_activity?
"One row per server process, showing database OID, database name,
process ID, user OID, user name, current query, query's waiting
status, time at which the current transaction and current query began
execution, time at which the process was started, and client's address
and port number. The columns that report data on the current query are
available unless the parameter track_activities has been turned off.
Furthermore, these columns are only visible if the user examining the
view is a superuser or the same as the user owning the process being
reported on."
