Wouldn't it just take the proposed pg_dump change to get that? rule
e2 says we'll store 0 in reltablespace, even if the user does
TABLESPACE pg_default, so there's no requirement to adjust the hack in
heap_create to put any additional conditions on when we set
reltablespace to 0, so it looks like none of the patching work you did
would be required to implement this. Right?
The good part about that is that its consistent with what happens if
the user does TABLESPACE pg_default for any other object type that
supports tablespaces. i.e we always store 0.
