I have a problem where postgresql 9.3 got stuck, and the number of postgresql processes increased from about 15 to 225 in 10 minutes.
I ran the query: select pid, query_start, waiting, state, query from pg_stat_activity order by query_start; But it showed mostly select statements -- all of them the same one, with a couple of joins. They are not in a waiting state but have been running for over 2 hours. I also checked for locks with the query on http://wiki.postgresql.org/wiki/Lock_Monitoring But it returned no locked tables. So what does this mean? Is the select query getting stuck? -- Si Chen Open Source Strategies, Inc. sic...@opensourcestrategies.com http://www.OpenSourceStrategies.com LinkedIn: http://www.linkedin.com/in/opentaps Twitter: http://twitter.com/opentaps
