Yes, its an obvious gap in their offering. I assume they wrap pg_upgrade in their RDS upgrade process, but of course it is in-place and requires downtime. Their multi-AZ replication is a high-availability solution but the primary and secondary must both be the same version of PostgreSQL, useless for major upgrades. For our upgrade 9.6 -> 13.4, we had the added complication that we used PostGIS which added a kink to the upgrade path. A reliable, caveat-free, simple AWS-provided logical replication solution for zero DT cluster upgrade was sorely missed and the downtime on the recommended path was painful. |
