I'm a bit confused, but what kind of pg_dump support you're talking about?
After a quick glance I don't see so far any table access specific logic there.
To check it I've created a test access method (which is a copy of heap, but
with some small differences) and pg_dump worked as expected.

As a side note, in a table description I haven't found any mention of which
access method is used for this table, probably it's useful to show that with \d+
(see the attached patch).
