Обсуждение: cstring datatype

Awhile ago, I remember discussion about having a 'cstring' datatype in
pgsql with builtin understanding that to convert to cstring you need to
use xxx_out and to convert from cstring you need to use yyy_in.

Anything came out of this discussion? It seems it'd be a great way to
have easiest datatype conversions where its possible at all.
(I.E. data::foo::cstring::bar would do (essentially) bar_in(foo_out(data))

Thanks

Nothing's been done yet, but it still seems like a good idea.

There are a number of related issues that I'd want to see tackled
at the same time, all arising from the overuse of type OID zero to
mean several different things.
