We have a small Stolon setup with 3 keepers, a Sentinel and a proxy. Keepers run PG11.
In order to upgrade to PG14 I am exploring a pg_dump/pg_restore upgrade path. Since we use AWS persistent volumes, the idea is to:
pg_dumpon the stolon-proxy (or should it be the master?)
- bring the cluster down
- mount the 3 volumes in a PG14 container
- replace the /postgres directory with a fresh
- make changes in
pg_hba.confsince we have some custom entries there.
- bring the cluster back up
pg_restoreon the proxy (or should it be the master?)
Is this anywhere near an accepted way of upgrading?
