Description:

Hello,
does the Postgresql oledb driver support Insert/Update operation?
I get the error E_NOINTERFACE (0x80004002) on Insert function.

see the code:

  CoInitialize(NULL);
    CDataSource db;
    CSession session;
    CDBPropSet    dbinit(DBPROPSET_DBINIT);

  dbinit.AddProperty(DBPROP_AUTH_INTEGRATED, "SSPI");
    dbinit.AddProperty(DBPROP_AUTH_PERSIST_SENSITIVE_AUTHINFO, false);
  dbinit.AddProperty(DBPROP_AUTH_USERID, "myuser");
  dbinit.AddProperty(DBPROP_AUTH_PASSWORD, "pass");
    dbinit.AddProperty(DBPROP_INIT_CATALOG,  "mydatabase");
    dbinit.AddProperty(DBPROP_INIT_DATASOURCE, "127.0.0.1");
    dbinit.AddProperty(DBPROP_INIT_LCID, (long)1029);
    dbinit.AddProperty(DBPROP_INIT_PROMPT, (short)4);
    hr = db.OpenWithServiceComponents("PostgreSQL.1", &dbinit);
    hr = session.Open(db);

  CDBPropSet propsetI(DBPROPSET_ROWSET);
    propsetI.AddProperty(DBPROP_IRowsetChange, true);
    propsetI.AddProperty(DBPROP_UPDATABILITY, DBPROPVAL_UP_CHANGE |
DBPROPVAL_UP_INSERT | DBPROPVAL_UP_DELETE);
  propsetI.AddProperty(DBPROP_CANFETCHBACKWARDS, true);

  {
    TRY_HRESULT(hr)
    CCommand<CAccessor<CTEvent> > t;
    hr = t.Open(session, "select * from abc", &propsetI);
    t.m_EVENT_ID = 123;
    t.m_idstatus = DBSTATUS_S_OK;
    hr = t.Insert();
    t.Close();
    CATCH_HRESULT(hr)
  }
