The OVERLAPS special SQL-construct is converted into the 'select
overlaps(...)' function call, which isn't allowed because OVERLAPS is a
keyword. *That* is where the parse error is coming from.
To fix this you simply need to double-quote "overlaps" when it's used as a
straight function call. See how substring does it in pg_proc.h.
