Hi all,
I’m getting:
- - -
pg_dump: error: Error message from server: ERROR: canceling statement due to conflict with recovery
ClientBeforeJob: DETAIL: User was holding a relation lock for too long
- - -
I have a 3-level streaming replication setup:
primary -> standby1 -> standby2
standby2 is for backup only and shows above error.
Both standbys have
hot_standby_feedback = on
Nvertheless the error happens.
Why?
How can I fix it?
Pause recovery on standby2 with pg_wal_replay_pause(), run pg_dump, and then resume recovery with pg_wal_replay_resume().
