Previously:
- PL/pgSQL cursors were non-scrollable
- DECLARE CURSOR cursors were not non-scrollable by default
The new docs say it is "query dependent", whereas previously the default
was non-scrollable. That sounds like a change in the default behaviour,
so I'm trying to dig a little deeper.
Are you saying that if I don't say anything at all then a cursor will be
non-scrollable?
