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. -- Michael Fuhr
