Sounds fine to me as well.  The LIMIT TO and EXCEPT clauses are
optional, so using TailMatches() looks fine.

+   else if (TailMatches("FROM", "SERVER", MatchAny, "INTO", MatchAny))
+       COMPLETE_WITH("OPTIONS")
Shouldn't you complete with "OPTIONS (" here?

It would be good to complete with "FROM SERVER" after specifying
EXCEPT or LIMIT TO, you can just use "(*)" to include the list of
tables in the list of elements checked.
