IMPORTANT: The default value of `startDelay` has now been changed to 3600 seconds, equivalent of 1 hour. Previously, it was set to 30 seconds. This patch also replaces the livenessProbe's initial delay with a more proper Kubernetes startup probe to deal with the start of a Postgres server. Both the startup probe and the higher default time should improve the self-healing capabilities of larger Postgres deployments where the default value of 30 seconds was not sufficient for example to complete a crash recovery operation, causing infinite restarts.

this patch provide the startupProbe support for postgres pod,
the failureThreshold of startupProbe is calculated by startDelay / PeriodSeconds,
while PeriodSeconds is use default 10 seconds. startDelay by default is 3600
