Apparently, there is something in either the ODBC driver itself or MS
Access that expects to be able to do "WHERE xmin = integer". Since we
supply no such operator in the standard distribution, one has to kluge
up the operator as illustrated. Of course, this code will break if we
go to 8-byte XIDs ...
