dblink is outdated, postgres_fdw is current.

dblink may not be getting lots of improvements, but it is maintained to the same standards as postgres_fdw is. FDW inhibits parallel queries, on both sides.  dblink maintains that possibility, (while tedious to do in a useful way).  Also, FDW cannot push UDF calls, while dblink can if you manually write them into the sent query.
 
Cheers,
