# Class: postgresql::params
#
# The postgresql configuration settings.
#
# Parameters:
#
# Actions:
#
# Requires:
#
# Sample Usage:
#
# TODO: add real docs
# This class allows you to use a newer version of postgres, rather than your
# system's default version.
#
# If you want to do that, note that it is important that you use the '->',
# or a before/require metaparameter to make sure that the `params`
# class is evaluated before any of the other classes in the module.
#
# Also note that this class includes the ability to automatically manage
# the yumrepo resource. If you'd prefer to manage the repo yourself, simply pass
# 'false' or omit the 'manage_repo' parameter--it defaults to 'false'. You will
# still need to use the 'params' class to specify the postgres version
# number, though, in order for the other classes to be able to find the
# correct paths to the postgres dirs.
