PG17 compatibility: Check whether table AM is default (#7747) 

PG 17 added support for DEFAULT in ALTER TABLE .. SET ACCESS METHOD

Relevant PG commit:
d61a6cad6418f643a5773352038d0dfe5d3535b8
d61a6cad64

In that case, name in `AlterTableCmd->name` would be null.
Add a null check here to avoid crash.
