"Recordset is read-only" with wine and unixodbc - Mailing list pgsql-odbc

I am trying to excute under wine an application (MFC VC6++) which works
fine under Windows (XP,7...), using ODBC and window pgsqlodbc. I try to
use it under unix pgsqlodbc  and unixodbx (under debian jessie amd64).
I hade some difficults to connect under i386 architecture but now it
works fine, except when I try to modify a record of the table with a
Crecordset.

I get the a "Recordset is read only" message on an application that
works fine under windows.
I use for odbc.ini :

[Mydatabase]
Description=PostgreSQL
Driver=PostgreSQL ANSI
Trace=Yes
TraceFile=/tmp/psqlodbc.log
Database=mydatabase
Servername=10.8.0.1
UserName=uuuu
Password=pppp
Port=5432
ReadOnly=No
RowVersioning=No
ShowSystemTables=No
ShowOidColumn=No
FakeOidIndex=No
ConnSettings=

Thank you for your help.
I can modify the source of the application if it is needed. I have tried
to use dynamic cursor but I got the result that it is not supported by
the driver.
