Sounds like you're looking for the pg_stat_activity view. See "The
Statistics Collector" in the "Monitoring Database Activity" chapter
of the documentation.
http://www.postgresql.org/docs/8.1/interactive/monitoring-stats.html
To see command strings you'll need to enable stats_command_string
in postgresql.conf. This setting is off by default in 8.1 and
earlier; enabling it can have a noticeable performance impact.
Performance is improved in 8.2, which will enable stats_command_string
by default.
