In any case, what you want to is use transactions. I think the confusion occurs because in some (many?) client-side languages you inititiate a transaction by setting auto-commit to off (JDBC and ODBC do this) in the client-side driver. In the case of the PostgreSQL JDBC driver, this causes a BEGIN command to be sent to the server. I would imagine ODBC does the same.
