ODBC with postgresql v6.5beta1

Hi,

I already asked this on pgsql-general and didn't get any responses.

I'm using PostgreSQL v6.5beta1 (mainly because it said it supports the INTERSECT
command) and iodbc 2.50.2. I've compiled everything ok and I can start the
postmaster and issue commands from psql. However, when I try to connect to the
database using an ODBC program I get the following error from the postmaster:

pq_recvbuf: unexpected EOF on client connection

Any ideas as to what might cause this?

Thanks,
Rich
