Thanks for updating the patch!

Based on your patch, I'm thinking of simplifying the code like this:

-       else if (Matches("GRANT", MatchAnyN, "ON", MatchAny, MatchAny))
-               COMPLETE_WITH("TO");
-       else if (Matches("REVOKE", MatchAnyN, "ON", MatchAny, MatchAny))
-               COMPLETE_WITH("FROM");
+       else if (Matches("GRANT|REVOKE", MatchAnyN, "ON", MatchAny, MatchAny) &&
+                        !TailMatches("FOREIGN", "SERVER") && !TailMatches("LARGE", "OBJECT"))
+       {
+               if (Matches("GRANT", MatchAnyN, "ON", MatchAny, MatchAny))
+                       COMPLETE_WITH("TO");
+               else
+                       COMPLETE_WITH("FROM");
+       }

Probably I failed to get your point here. Could you clarify what you meant?
