Doc Text:	When attempting to run a PostgreSQL slave pod from the upstream replica template, the pod could get stuck in CrashLoopBackOff status, citing a "MEMORY_LIMIT_IN_BYTES: unbound variable" error. This bug fix ensures that cgroup limits are properly handled for such pods, and as a result this issue no longer occurs.	Story Points:	---
