Обсуждение: Long SQL Update Question

So I kicked off a SQL transaction that has been running for 30+ minutes. Is there any way to monitor it to know if it
haspossibly hanged or not? To be fair, it is an update on 4+ million rows, so I expect it to run for a bit. But any
statsor metrics I can get would be helpful.<br /> Cheers,<br /> dylan<br /> 

You can turn on logging ... but your transaction would be even slower
after that.

The following links should give you some pointers:
http://www.postgresql.org/docs/8.1/static/monitoring-stats.html
http://www.postgresql.org/docs/8.1/static/monitoring.html

Also try Nagios monitoring plugins for PostgreSQL. Get it from pgFoundry.
