Use pg_hba in postgresql::hba and allow all user to authentify with md5 on template1 database (required for /usr/local/sbin/pp-postgresql-user.sh)
Don't use composite namevar in postgresql::hba wrapper
Only allow created user to connect to template1 via md5 in postgresql::user
Reload postgresql after changing pg_hba
