Simplifies conditional logic for writing pgpass config file
Simplifies conditional logic for writing pgpass config file

We only want to write the file during initial provisioning, and ignore
it otherwise, so it may be customized with auth secrets not maintained
in Ansible vars. Rather than stat/register, we can simply set force=no
for the `template` module, and Ansible skip rather than clobber the file.
