There is nothing to do with locale. The same database has been working just fine for 2 years. Why should this be an issue now? When I ran the EXPLAIN SELECT, the database was hanging. Or taking too much time (waiting for 5 minutes), or whatever. I cancelled it. That's the problem. It works, then it doesn't. Then it works again. I am guessing it could be the load, but there's nothing new in terms of load that should be causing this! ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
