Changelog: Alter type options

It seems that we don't support propagating commands related to base
types. Therefore Alter TYPE options doesn't seem to apply to us. I have
added a test to verify that we don't propagate them.

Changelog entry on pg13:
Add ALTER TYPE options useful for extensions, like TOAST and I/O functions control (Tomas Vondra, Tom Lane)
