Well, the obvious reason is that it's hard to tell what the user meant,
so bailing is the safest response.

So you're suggesting that "SELECT 1/0;" should terminate a transaction,
but "SELECT 1//0;" should not? How about "ROLBACK;"? It gets pretty
squishy pretty fast when you try to decide which sorts of errors are
more important than others.
