There surely are use-cases for true rational arithmetic, but I'm
dubious that it belongs in core Postgres. I don't think that enough
of our users would want it to justify expending core-project maintenance
effort on it. So I'd be happier to see this as an out-of-core extension.
(That'd also ease dealing with the prospect of having more than one
variant, as was mentioned upthread.)
