Hello All,
I am facing some problems while taking logical backup of my database using pg_dump. We have set up our infrastructure such that the logical backups are taken on our DR. Our intention here is to avoid substantial load on our primary server. We also pause and play wal files using pg_wal_replay_pause and pg_wal_replay_resume before and after pg_dump. However, at the time of pausing the wal replay, if there is a table under ACCESS SHARE MODE, the pg_dump cannot complete the backup.
Can anyone suggest any better solution to take a logical backup using pg_dump where the table lock doesn't result in failure of the logical backup?
PS: we are using PostgreSQL 10.12
Thanks,
