defaulted psql_path to postgresql::server::psql_path

[crayfishx]

The psql_path variable declared within the postgresql::server::service class defaults by calling the default directly from params rather than from the parent service class like other variables. Since these are not parameters, this makes psql_path impossible to override using class params/hiera. It looks like this was done in error as $postgresql::server::psql_path exists and defaults to the params entry.

This fix defaults it to $postgresql::server::psql_path and should give the same default behavour but allow you to override postgresql::server::psql_path: foo in Hiera.

I don't know if it's related, but I'm trying to use the module with the postgresql package from SCL and it has weird paths. For example, psql is at /opt/rh/rh-postgresql96/root/usr/bin/psql. If I try to use the module, the connection validator fails, most likely because it cannot find the psql binary. I don't know how to override it.

Nevermind, it looked it worked OK. The problem is that when it calls psql from the SCL package, it cannot find a shared object. I installed the non-SCL psql and removed my psql_path entry and it works ok.
