Summary: connection problem with postgresql driver 8.03.0100 to postgresql 8.3.0

Initial Comment:
I compiled postgres odbc driver version 8.03.0100, but when I try to connect
to a 8.3.0 postgres database, then there connection/authentication problems
happen:

isql FIS MyUser MyPassword -v
[28000][unixODBC]Communication error during authentication;
Error while reading from the socket.
[ISQL]ERROR: Could not SQLConnect
dbuser(at)dbhost:~> isql FIS MyDatabase MyDatabase -v
+---------------------------------------+
| Connected! |
| |
| sql-statement |
| help [tablename] |
| quit |
| |
+---------------------------------------+
SQL>

I can only connect to the database by a chance of 1/10. Also when I get
connected, then when I try entering a SQL statement, I get error messages
about not being connected anymore.

and below the postgres log from the tries:

LOG: connection authorized: user=MyUser database=MyDatabase
LOG: unexpected EOF on client connection
LOG: disconnection: session time: 0:00:00.002 user=MyUser

This is the part of the configuration from my odbc.ini:
[FIS]
Description = PostgreSQL DB
Driver = PostgreSQL
commlog = yes
Database = MyDatabase
Host = localhost
Server = localhost
ServerName = pdtest106.pdtest.intern
Username = MyUser
Password = MyPassword
Port = 5430
Protocol = 6.4
ReadOnly = No
RowVersioning = No
ShowSystemTables = No
ShowOidColumn = No
FakeOidIndex = No
ConnSettings =

Actually, I have no idea, what the protocol version number means. The
version 6.4 was the one I found most of the time in the net. I also tried to
set it to 8.3, and 8.3.0, but with no difference. Any pointer to an
explanation would be great.

when I exchange the odbc driver file, with an older one, odbc drvier version
8.1.2, then I do not have connection/login problems at all.
