Re: FUD!! ODBC will not be supported by Microsoft in the future

If you look in the pg 7.3 docs it seems to state that FETCH can fetch
backwards. Does this mean that the backend needs to materialize the whole
recordset but could return just the last n records to the client? If so
then that would be different than the current psqlODBC state of affairs and
would be a net gain as it would reduce network traffic.

Any thoughts?
