You should always include relevant info such as which version of postgres you are using.

If the stats are enabled (stats_start_collector and stats_command_string in 8.1) you can see running queries in the
pg_stat_activitysystem view. 

You can also set the logging to show all commands (in 8.1 set log_min_duration_statement to 0 (and perhaps set
log_statementto 'all') and the designated log will show all queries. 

Queries which have gone away will prove to most elusive, I fear ... not running at all could be a symptom of locks or
contentionsfor tables/rows, etc. More information might help people give you a better answer.
