Kubernetes - Stateful set ins't persisting data after cluster reboot

I have a Kubernetes cluster and I installed Postgresql and TeamCity-Server, but, as my enviorment is a sandbox, I always shutdown after comercial time and start on the next day. Said that, my data from Postgresql and TeamCity-Server always get lost and I think I'm missing some here, here is all my YAMLs, from both services:

Postgresql:
