SELECT * FROM pg_stat_activity;

If the current_query column says "<command string not enabled>"
then edit postgresql.conf, set "stats_command_string = true" (and
make sure it's uncommented), and restart or reload the backend.

For more information, see the "Monitoring Database Activity" and
"Server Run-time Environment" chapters in the documentation.
