configure install to prefer user location over system location

[coolaj86]

The default location of the hba config is something like:

/etc/postgresql/14/main/pg_hba.conf

But what we use in these scripts is a local user location:

/home/app/.local/share/postgres-10/var/pg_hba.conf

We may want to update the install script to disable the system postgres run the postgres with the user location - or abandon that idea and update the scripts to go the other way.
