[bitnami/postgresql-ha] Cloning huge data from primary node fails due to livenessProbe

[percenuage]

Description of the change

Update livenessProbe in order to check if process are in "data standby clone" step. If the synchronization from primary are longer than the livenessProbe fails, the replicas will restart in loop. It works for small data since it's fast but not with more than 20Go (I have 300 Go on primary on SSD and it has taken around 25 min to sync).

Maybe there is a special command from PG to check but I haven't found any.

Personal thanks to @exename (#4894 (comment))

Benefits

Allows flexibility to add replicas during the run with existing data.

@carrodher "All checks have passed" :) I don't know when you will merge but since the time flies, there is conflict appears on CHANGELOG and chart.yaml.

Ideally, this step involving syncing data on standby nodes should be done in a init-container so it doesn't affect probes.
