BTW, the situation on the input side is a bit different: record_in is
volatile because domain_in is, and I think we'd better leave that alone
since it's not too hard to believe that a domain might have volatile
CHECK expressions. If we had arrays of domains, anyarray_in would have

Or we could decide that volatile domain CHECK expressions are un-sensible
and just relabel all these input functions as stable, which would make
everything consistent. Thoughts?

I am working on to_array, to_string functions and I am looking on

What's wrong with that? current_date is the part

string_to_array() seems fine to me: it's a predictable transformation
from text to text. However, I think that there really is an issue with
array_to_string(), because that takes an anyarray and invokes the array
element's type output
