I thought about this some more. I think we could get rid of attusertypmod
and just hardcode it as -1. The idea would be that if you ask for an
encrypted column of type, say, varchar(500), the server isn't able to
enforce that anyway, so we could just prohibit specifying a nondefault
typmod for encrypted columns.
Why not just use typmod for the underlying typmod? It doesn't seem like
encrypted datums will need that? Or are you using it for something important
there?
Yes, the typmod of encrypted types stores the encryption algorithm.
(Also, mixing a type with the typmod of another type is weird in a
variety of ways, so this is a quite clean solution.)
