We do a variety of variants on the following to find long running things. The one below is looking for 'idle in txn' txns longer than 20 minutes.
SELECT NOW() - coalesce(xact_start, state_change) AS duration, * FROM pg_stat_activity WHERE NOW() - coalesce(xact_st
art, state_change) > interval '20 minutes' AND state = 'idle in transaction' ORDER BY xact_start
art, state_change) > interval '20 minutes' AND state = 'idle in transaction' ORDER BY xact_start
