Actually, Oracle implicitly COMMIT's all open transactions if someone
performs a DDL statement on the table (or even the same schema?).
What other databases do is not necessarily correct[1]. In this case
PostgreSQL does the right thing; something went wrong, queries after the
error may very well depend on that data - you can't rely on the current
state. And it's what the SQL specs say too, of course...
[1] I'm not trying to imply that what PostgreSQL does is (in general).
