From 5307eecdcdf38f243206d696da2521773246f589 Mon Sep 17 00:00:00 2001 From: Vinayak Hariharmath Date: Mon, 19 Aug 2024 16:44:27 +0530 Subject: [PATCH] db upgrage: upgrade postgres 15 to postgres 16 The Postgres upgrade from 15 to 16 or any later versions can be done by adding the env variable named POSTGRES_UPGRADE = copy in the pg db pod. More about upgrade process is here: https://www.postgresql.org/docs/current/pgupgrade.html In our case, we achieve the upgrade by setting this env var in noobaa-db-pg STS. Once after upgrade is done, we have to remove the POSTGRES_UPGRADE env from the STS. Otherwise pg db pod fails to come up because the db pod check PG directory version against upgrade image version and exits if there is no upgrade required and POSTGRES_UPGRADE is still provided. To remove this env, we store the upgrade status in noobaa-core CR after the PG upgrade and refer the same status during db reconcile. If the upgrade is already done, we remove this env from desired sts status. This will help to upgrade the db smoothly.
