Thanks, Tom! I found some long ago (8.3) code that created 15 implicit casts (AND the needed functions within pg_catalog that I had been using through the years, so I was able to drop them and move forward. Ah, memory lane.

Hm, there wasn't any such function in 9.6 either, so I suspect you've forgotten some critical details about how these casts got created. But anyway, if you really want that behavior, creating the cast "WITH INOUT" is probably the best way to do it.
