All of which may be useful, and may not. Right now DBD::Pg is trying to
move further from libpq, rather than binding closer to it, mainly because
it's a huge dependency burden and it takes forever to add new features.
For example, if this got accepted and put into 8.4, the very earliest DBD::Pg
could take advantage of the code would be mid 2009 (assuming an optimistic
release schedule). Even then, only once 8.4 was widely in use (2010?) would the
average DBD::Pg be compiled against it. And that means lots more forking to handle
the old version until then. But don't take my non-use personally: as you say, this
may be more helpful towards C programmers. I only weighed in because I was asked
to specifically.

Did you even post on -interfaces? I would think that would be the first place
to post, certainly before -patches.

Yes, we move them into and out of the server, and into and out of Perl arrays
in the process. I'd be happy to give the new way a try however: have you
any sample code and documentation? Emphasis on the latter.
