only table oc_migration being created while installing nextcloud on k8s using helm chart with postgresql-ha and pgpool enabled

Describe your Issue

Hello everyone..
we are using Nextcloud helm chart to install nextcloud on k8s..an external postgresql is installed via Postgres-HA bitnami helm chart..and a user called nextcloud has been given a full access to a database called nextcloud as well.several check has been done in order to make sure everything is okey with database..
when we install nextcloud it goes to a part of Initializign nextcloud and then provide some error about missing tables in postgress.intersting thing is only one table is being created which is called oc_migrations and that's why we are sure there is no problem due the connectivity between nextcloud and postgesql...
another thing that is very wired is that sometime the installation progress complete without any problem and many table get created with oc_* prefix.
it is worth to mention that we disable liveness and readiness to give the service sufficient time to do it's initialization.
many times we delete the whole service and install it again but many time we faced the same problem.

Describe your Environment

• Kubernetes distribution: rke-v1.24.8

• Helm chart version -> nextcloud-3.5.19

• App VERSION -> 27.0.0

Start by reproducing the installation with nextcloud-3.5.19, App 27.0.0, PostgreSQL HA, and pgpool enabled, then inspect the chart configuration and initialization ordering. Trace the database setup entry points in lib/private/DB/MigrationService.php and lib/private/Setup/AbstractDatabase.php, comparing successful and failed runs. Done means a fresh deployment consistently completes and creates the expected oc_* tables.
