Keycloak pods failing

The most common cause of Keycloak pods being down is Postgres. Current health checks for Postgres are insufficient, we have a ticket to address it:

So, it is important to check Postgres logs as well in this case. If there is no obvious pointers (disk space, etc) - delete and recreate Postgres pods, then restart Keycloak.
