Scrollable cursors are not supported by the server. Updatable result
sets were not yet implemented.

There's hardly any possibility to scroll backward. Scrolling forward
is easy - you just count rows. Updatable cursors can be replaces by
positioned updates: you have to set the cursor name and then use
construct "UPDATE ... WHERE CURRENT OF my_cursor".
