Yes, it would be nice to fix that.

+ else if (HeadMatches("CREATE", "EVENT", "TRIGGER") && TailMatches("EXECUTE"))
+ if (pset.sversion >= 110000)
+ COMPLETE_WITH("FUNCTION", "PROCEDURE");
+ else
+ COMPLETE_WITH("PROCEDURE");

PROCEDURE is documented as deprecated as of v11 for CREATE TRIGGER and
CREATE EVENT TRIGGER. Wouldn't it be better to just complete with
FUNCTION for a v11 or newer server? I think that we want to encourage
users to use EXECUTE FUNCTION if possible.
