The time taken to get something into the standard is a lifetime in
computing terms. If my client has a need for a UDF they need it now, not
when the standards committee gets around to thinking about it.
Many UDTs will be specialised to a single user, and never be candidates
for inclusion in the standards. Excluding any type that isn't in the
standard would be to throw away one of Postgres' greatest strengths, one
we are justly proud of. Maybe you don't care about that, but we do, and
our clients do.
In any case, a standard for UUIDs would almost certainly not specify how
it is to be stored, which is where we got into this discussion.
This debate started with a misconception about how Postgres actually
stores UUIDs, and doesn't seem to have gained much point since then.
