One point to make here is that libpq doesn't currently expose the full
power of the v3 protocol, and it's entirely possible that there are
things ODBC needs that you just can't get at in current libpq.  We'd
certainly be open to well-designed extensions of libpq's API to fix
any such problems ... but keep in mind that if such is needed, you'd be
tying ODBC to 7.6 or later libpq.  Might pose some distribution
problems.

I think that reimplementing ODBC on top of libpq would probably be
a good plan in the long haul, since in theory it ought to reduce
maintenance effort in the long haul.  But it won't be a quick fix.
