Title: Postgres Adapter Bug Fix

There was a bug in the create_database method of the postgresql adapter that would prevent a database from being created if the options hash was empty. This was fixed by forcing the sum method to start with an empty string instead of the default 0.

The actual error is "can't convert Fixnum into String"
