Tough question.

First PL/Proxy.  One objection against PL/Proxy is that it might interfere
with SQL-MED implementation.  I don't think its the case because both
solve slightly different problems.  SQL-MED brings remote tables "local"
(importing whole schemas and such).  PL/Proxy allows remote calls
and load balancing/distribution.  I think it might be even valuable to
use these two together (building on strengths of these two).

By the way, while reading SQL-MED standard I didn't find obvious
way of calling ad-hoc remote tables (as in Oracle's db links for
instance), only either creating remote tables or running in "passthrough"
mode. I guess I did miss something, I was only skimming through it.

As for citext I am less enthusiastic.  While I understand the need for
case insensitivity, it feels hacky.  Like something which screams to
be more general but fails to do so.  And if citext, how about
say rawtext (locale-less text)? [1]  utf8text (utf8 compilant text
available even if POSIX localle is used) and so on. ;)

I would still want citext to get into contrib, but my heart is strongest
with PL/Proxy here.

   Regards,
       Dawid

[1]: Actually I think it would be better to "upgrade" bytea into something
like locale-less, 8-byte, raw-text-alike.  I mean, be able to do regex
queries, LIKE queries, etc on it.  I sometimes miss that kind of functionality.
