Meh. It's happened a couple of times now :-)

Hmm, I'd forgotten about that. We do it because it allows us to run
non-transaction safe DDL in separate transactions (which is required
in 8.3). Actually, this is not a major issue - all that will happen is
that the server will reject the SQL in 8.3+ if the user includes no
transaction safe DDL with other commands (or blindly accept it in
earlier versions). I say we just split the text control on those two
dialogues, per option 1.
