Hi, An SQL (with only information_schema related JOINS) when triggered, runs with max CPU (and never ends - killed after 2 days). - It runs similarly (very slow) on a replicated server that acts as a read-only slave. - Top shows only postgres as hitting max CPU (nothing else). When query killed, CPU near 0%. - When the DB is restored on a separate test server (with the exact postgresql.conf) the same query works fine. - There is no concurrent usage on the replicated / test server (although the primary is a Production server and has concurrent users).
Questions: - If this was a postgres bug or a configuration issue, query on the restored DB should have been slow too. Is there something very basic I am missing here? If someone asks for I could provide SQL + EXPLAIN, but it feels irrelevant here. I amn't looking for a specific solution but what else should I be looking for here? p.s.: All postgres servers are running the v9.3.10 - robins -- - robins
