Question about psqlODBC cursor supporting.

["Hu, Ming \(Ivan\)" <huming(at)alcatel-lucent(dot)com>]

Hi, 

I am new to psql ODBC, cann't find detailed info about psqlODBC cursor
supporting (or should be postgresql cursor support?).

Can psqlODBC support cursor based updating and deleting, whether
operationa on other transaction can influence cursor result set in time?

Or somebody can route me to any materials, thanks very much.

Best Regards
Ivan
