I just tried the CVS release (psqlodbc-08.02.0002).
It is a lot better: SQLSetPos() does not return the previous error for update or
delete but it still does not work.
The update returns:
SQLSTATE: 07005
NATIVE CODE: 15
MESSAGE: update list null
The delete returns:
SQLSTATE: 42601
NATIVE CODE: 7
MESSAGE: syntax error at or near "where";

Here is the beginning and a snippet of the psqlodbc log around the "update"
error:

I have also the "mylog" trace I can send if needed.

Help!
