Ah. That sounds like the problem.

It's even simpler. The protocol started at 0.0, was 1.0 for v6.3, and
will be 2.0 for v6.4. But on the surface it looks like we are OK for
now, unless Postgres doesn't really like v6.3 packets:
/opt/postgres/current/src/interfaces/odbc.new/connection.h:
#define PG_PROTOCOL_LATEST PG_PROTOCOL(1, 0)
/opt/postgres/current/src/interfaces/odbc.new/connection.c:
sp.protoVersion = (ProtocolVersion) htonl(PG_PROTOCOL_LATEST);

Yeah, it didn't help :) I hope to get somewhere on this soon, and I can
send patches or full sources which include changes. No point in making
you guess on what actually worked...
So, any more ideas/suggestions on how to get this working?
