I am facing a weired issue in PG 9.0.3. Sometime via application UPDATES are not changing data in the database but in postgres logs its also not raising any error. It is happening 2-3 times in a week. I have tried but not able to reproduce this error. fsync is ON. We are not using hibernate and no pg pool or any other tool inside database. The application running from last 4-5 year but from last few days we are experiencing some times UPDATE is not updating records in database, without giving any error. No changes has been made in database or server recently.
UPDATE dbpush_camp_main SET status=7 WHERE camp_id IN(137721)
Below is the logs of database.
<snip> Jul 30 12:40:36 dell16 postgres[11088]: [11-1] 2012-07-30 12:40:36 IST [11088]: [10-1] user=postgres,db=dbpush xxxxxxxxxxxxxxxxxx(43225)LOG: statement: START TRANSACTION Jul 30 12:40:36 dell16 postgres[11088]: [12-1] 2012-07-30 12:40:36 IST [11088]: [11-1] user=postgres,db=dbpush xxxxxxxxxxxxxxxxxx(43225)LOG: statement: UPDATE dbpush_camp_main SET status=7 WHERE camp_id IN(137721) Jul 30 12:40:36 dell16 postgres[11088]: [13-1] 2012-07-30 12:40:36 IST [11088]: [12-1] user=postgres,db=dbpush xxxxxxxxxxxxxxxxxx(43225)LOG: statement: COMMIT Jul 30 12:40:36 dell16 postgres[9368]: [5-1] 2012-07-30 12:40:36 IST [9368]: [4-1] user=postgres,db=dbpush xxxxxxxxxxxxxxxxxx(43187)LOG: statement: SELECT status FROM dbpush_camp_main WHERE camp_id=137721 </snip>
The size of database is 237GB, AND dbpush_camp_main table size is 37MB with 36888 records and one primary key. status is a integer field.
Please share your thoughts. Thanks a lot in Advance !!
