This has been discussed before. I think the reason for not doing it
has been the difficulty of coming up with a useful warning that explains
what will work and what won't. You suggest

> WARNING: psql version is 7.4.1, but postgres server version is 7.3.4.
> Some psql features may not function as expected.

but you've got to admit that's pretty vague and unhelpful.
