OK, this is whats happening:

1) Command Prompt (Joshua's company) are writing a new ODBC driver
(ODBCng), which is in very early stages of development. That driver is
not developed here, nor is it the 'official' PostgreSQL driver (though
we are pleased that CP are widening the choices available to users).

2) psqlODBC (the official driver) has changed a bit over time:

- The original driver (ie. <= v08.00.xxxx) implemented it's own comms

- The 'new' driver (08.01.xxxx) uses libpq instead of it's own comms
layer which means that it uses both the v2 and v3 wire protocols as
appropriate, and adds features such as SSL, Kerberos support, and
.pgpass/pgpass.conf support. This is the driver we recommend you use
(currently 08.01.0200).

- Another driver variant (actually a fork of the code from
07.03.0209ish) is currently being evaluated as a possible replacement
for the current version. It has been enhanced significantly and includes
similar changes to those in 08.01.xxxx, but implemented in a very
different way.

Regards, Dave.
