Message-ID: <i9c60b$ifv$1@news.hub.org> (raw)
We currently have
log_min_duration_statement = 5000
and are seeing statements like the following logged
2010-10-16 05:55:52 EDT [6334]: [1-1] LOG: duration: 5572.517 ms
statement: EXECUTE <unnamed> [PREPARE: COMMIT]
2010-10-16 06:06:24 EDT [26856]: [1-1] LOG: duration: 5617.866 ms
statement: EXECUTE <unnamed> [PREPARE: COMMIT]
2010-10-16 06:06:24 EDT [20740]: [13-1] LOG: duration: 5210.190 ms
statement: EXECUTE <unnamed> [PREPARE: COMMIT]
2010-10-16 08:24:06 EDT [8743]: [1-1] LOG: duration: 6487.346 ms
statement: EXECUTE <unnamed> [PREPARE: COMMIT]
Questions;
1) What do these statements mean?
2) How do I dig deeper to determine why they are taking longer than 5 secs.
