Here's a much simpler SQL/MED support patch for dblink.

This enforces security in the same manner for FOREIGN SERVER connections
as that worked out over time for other dblink connections. Essentially,
the FOREIGN SERVER and associated user MAPPING provides the needed info
for the libpq connection, but otherwise behavior is the same.

I've also attached a doc patch.

Comments?
