PostgreSQL writes several following logs during the problem which I never
saw before 9.2.3:
LOG: process 4793 acquired ExclusiveLock on extension of relation
305605 of database 16396 after 2348.675 ms
I tried
* to downgrade to 9.2.2
* to disable autovacuum
* to disable synchronous commit
* to write less on the big tables
* to increase checkpoint segments
* to increase max connections
* to move pg_xlog to sepe
None of them helps to avoid downtimes. I could not find anything related
to it? Do you have any idea? Have you ever experience something like this?
