No, the problem is not with the ODBC driver.  The problem is that views in postgresql are static non-update-able by default.  So if you try to update and record in a view using a cursor or any other sql statement, you will get an error.

This problem can be fixed if your view meets the following criteria:

1) your view is based on only one table

2) your create rules for your view that define how updates to the view are to be handled/cascaded to the base table.

3) since postgresql rules can only handle update statements that affect only one tuple at a time, your cursor must only be able to update one record at a time.
