Idle hanging transactions from poorly written applications are the bane of my existence. Several months back one of them took down one of hour production websites for several hours.
Unfortunately, the only way to deal with them is to terminate the backend which is heavy handed and in some cases causes further damage. Something like pg_cancel_transaction(pid) would be nice; it would end the transaction regardless if in an actual statement or not. Similarly, transaction_timeout would be a lot more effective than statement_timeout. It's nice to think about a world where applications don't do such things, but in this endless sea of enterprise java soup I live it it's, uh, not realistic. This would be lot cleaner than the cron driven sweep I'm forced to implement now, and could be made to be part of the standard configuration across the enterprise. merlin -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
