Yeah. We're way off topic for partitioning, so I think it's best to just
table this discussion until someone comes up with a good idea.
It's not the end of the world to write some generic C code, and have
multiple types make use of it, e.g. PERIOD, PERIODTZ, INT4RANGE,
FLOAT8RANGE, etc. It's a little redundant and creates some catalog
bloat, but I'm not too concerned about it right now. Certainly not
enough to rewrite the type system.
