Only since 9.5, because GROUPING wasn't a keyword before that.

This is expected given that it's now partially reserved.

That would be a pg_dump bug, but it doesn't happen for me: I get

CREATE FUNCTION a() RETURNS TABLE("grouping" integer)
    LANGUAGE sql
    AS $$  select 1; $$;

Sure you're using 9.5 pg_dump?
