Yea!!!!! This fixes the problem. I will test the \g option in a few hours
after I have completely repopulated my data. How about adding a comment
about the importance of this patch? Thanks Tom for tracking this down so
quickly.
Thanks, Michael

Fixed. I had managed to break the empty-query response protocol on
Sunday --- odd that none of the regression tests detected this.
Sigh.

I now have a strong suspicion that this is caused by the same goof.
ODBC might issue an empty query during startup. (That used to be a
necessary part of the startup protocol; it isn't anymore, but ODBC
very possibly hasn't been changed.)
If you don't have CVS access and don't want to wait for tonight's
snapshot, here is the patch:

! pq_putbytes("I", 2); /* note we send I and

break;

Let us know if that helps...
