Makes sense to me.

Yes, if you are using a snapshot of 6.4 then the driver won't work because it is using 6.3 protocol.  And it uses
PG_PROTOCOL_LATEST
in its connect for the protocol version.  Maybe it should use 6.3.

How do you set the protocol version to be 6.3?  Is it just major number = 6 and minor number = 3?  Seems too simple.

Also, as far as compiling goes, I understand the driver has trouble compiling under Linux since the Translation DLL
stuffwas 
added.  Did you have to ifdef that stuff out for Non-win32?  If so, I guess I'll just put that into the official
source.
