Image in root user only when using local postgre db

Entry point requires root user, however, I prefer not using root user to start this image in our Kubernetes cluster

Affected lines in entrypoint script
>>>>>>>>>>
if [[ "$URL" = "jdbc:postgresql://127.0.0.1:5432/pulsar_manager" ]]
then
echo 'Starting PostGreSQL Server'

addgroup pulsar
