The postgres version is –
psql (9.0.7) From: pgsql-admin-owner@xxxxxxxxxxxxxx [mailto:pgsql-admin-owner@xxxxxxxxxxxxxx]
On Behalf Of Porwal, Utkarsh Dear All, I have a perl script which will attempt to drop/recreate some intermediate tables. This works by trying to acquire an access exclusive lock on the intermediate
tables. When there is a backup running through pg_dump, I see an entry in pg_locks/pg_stat_activity table for the above which is waiting for pg_dump to finish, which
is expected. Since backup on huge environment takes around 8 hrs to complete, I noticed that the entries waiting for locks are removed after certain amount of time which I
couldn’t record even though the perl script is still running. Do you guys know if the lock waiting will ultimately timeout and when? I don’t have any statement_timeout specified. Any pointers on this behavior? Regards, Utkarsh
