"No such attribute or function 'oid'"

Hi;
I'm using ODBC driver for windows, because I use Excel (Microsoft) to work
with data. When I try to get data from a Postgres table there is no problem;
but when I try to acces a view I get the mesage:
"No such attribute or function 'oid'"

When I try to access views from ACCESS2000 there is no problem
What is the cause of this? Can I resolve it?

Thanks and regards

Javier
