Is this fixed by the patch I sent in last night?  Your description does
not sound like what I would expect.  The bug I fixed was that PQfsize()
would return 65535 instead of -1 for a varlen field.  But neither libpq
nor psql make use of that value (which is why I hadn't noticed it was
broken).  Are you using some other frontend code that does depend on
PQfsize to return the right thing?
