But what about databases where connections and cursors really are
different?  That is, in Sybase you can submit SQL through either a
connection or a cursor, and that implies some meaningful difference to
the server.  Eg. some things are legal in a connection that aren't in
a cursor (don't ask for specifics, but we just saw an example two days
ago).

Of course if no other database does this sort of thing, it probably
doesn't need to be reflected in the standard.
