Merge lp:~marcoceppi/charms/precise/postgresql/ip-hostname-verification into lp:charms/postgresql

This completes the changes made in rev:30, since ip addresses require a full CIDR, and not all cloud environments provide hostnames, this fix will make sure that hostnames are passed to the template untouched which IP addresses get a /32 appended to the private-addresses. I could not verify this on my local, but the following code executes as expected in the interpreter http://paste.ubuntu.com/1641245/

instead of the join, or str('/') [ie. string a string], i'd suggest interpolation

ie. = "%s/32" % relation['private_address']

review: Approve

Thanks Kapil! I originally did concatenation via relation['private_address'] + '/32' but that produced weird hex values. I've updated to use interpolation as it's cleaner and easier to read.

Use interpolation instead of join
