Hello,

To detect required or autoincrement fields you should set the ExtendedFieldsInfo options to true like

in Delphi 2006 and lower IDE versions:

procedure TForm1.SQLConnection1AfterConnect(Sender: TObject);
const
coExtendedFieldsInfo = TSQLConnectionOption(502);
begin
SQLConnection1.SQLConnection.SetOption(coExtendedFieldsInfo, Integer(True));
end;

Starting with CodeGear RAD Studio 2007:

SQLConnection.Params.Values['ExtendedFieldsInfo'] := 'true';

more information about it you can find in the .. \Devart\Dbx\PostgreSQL\Readme.html file.
