PostgreSQL version: 8.0.1
Operating system:   Win XP SP2
Description:        Problem with PGAPI_SetPos
Details:

Environment:
    WinXP SP2/Visual C++ 6/MFC
    PostgreSQL 8.0.1 db
    ODBC 8.00.01.01

I'm accessing the Postgres from a VC++ application using the ODBC driver
mentioned.
All works fine (open the db, SELECT, ...) until I try to insert a row using
the CRecordset::Update() class method. This method is intended to insert to
the db all the records previously added in the recordset object.
Postgres returns the exception:
"Only SQL_POSITION/REFRESH is supported for PGAPI_SetPos"

Anybody has encountered with the same problem?
