Not essential for pgTAP, no, as we can just use the parts. It was the typmod bit that was missing.

I was just thinking about hitting the thesaurus entry for “canonical”, but I quite like reformat_type. It’s super clear
anddraws the parallel to format_type() more clearly. Will likely steal the name for pgTAP if we don’t add it to core.

I guess the questions are:
* What are the other use cases for it?
* How obvious is it how to do it?
For the latter, it could easily be an example in the docs.
