Use correct path for initdb and pg_ctl

[mzwennes]

Fixes #465

Motivation

initdb and pg_ctl are no longer available in the v0.3.0 image. Most likely this is due to a switch from alpine or to a newer version of PostgreSQL (13).

This change fixes the not found issues for both of these.

Verifying this change

• Tested it locally by building the image and running it
• Tested it on Kubernetes on a clean environment

Better add the binaries to the PATH in the dockerfile

ENV PATH="/usr/lib/postgresql/13/bin/:$PATH"

WDYT?

Tried to make this work by modifying PATH in the deployment, but since entrypoint user is root and the postgresql commands run as user "pulsar", the PATH var wasn't correct for that user and they failed. Better imo to use full path.
