contrib/dblink doesn't require them. It does have an option to use an
FDW instead of a libpq connection string to specify the connection
target. I had forgotten that that option got added in 8.4, before we
had any other working use for FDWs --- so maybe we should rethink the
decision not to backport this fix?

Add missing support for removing foreign data wrapper / server privileges
belonging to a user at DROP OWNED BY. Foreign data wrappers and servers
don't do anything useful yet, which is why no-one has noticed, but since we
have them, seems prudent to fix this. Per report from Chetan Suttraway.
Backpatch to 9.0, 8.4 has the same problem but this patch didn't apply
there so I'm not going to bother.
In the meantime, though, you do not *need* an FDW. dblink worked fine
for many releases before FDWs existed, and it still does work without
'em.
