protopg - protopg: * Adding support for "CREATE SYNONYM".

Log Message:
-----------

* Adding support for "CREATE SYNONYM". Actually PG does not have such thing :( until
you apply patch. Because of this, the rules just output commented statements.

* Adding regression file for the "CREATE SYNONYM". Since PG does not have
such thing, *.expected file is ommited.
