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
