C++ interfaces

ok, I think I have sufficient reason to go ahead with a complete rewrite
of the libpq++ libs. First the connection functions in libpq are
defined as static which makes them unsafe in a threaded environment. In
addition, I think a complete rewrite will allow us to implement the
ability to manage multiple concurrent sql commands more effectively than
with relying on the libpq lib.

I'm currently looking at the packet structures that the back-end and
clients must use. I've found that many packets are terminated with
0x5A. The docs don't mention this so I was wondering if anyone could
suggest why. An example is the packet which sends the backend key
data. Every time I have psql connect to postmaster, the postmaster sends
a packet with the secret key upon validation with 0x5A as the final
byte. Any ideas?

As far as maintaining both libpq and libpq++, the latter could use
some of the header files in libpq, such as pqcomm.h, to maintain
consistency of protocol defs across the backend and frontends.

That's where I am at right now. Anyone have advice/suggestions?
