Au contraire, rolling back a CREATE works fine. It's rolling back
a DROP that gives trouble ;-)

This does bring up a thought --- should psql's kill-the-script-on-error
option perhaps zap the script only for errors committed outside of a
transaction block? I'm not sure how hard it is for psql to keep track
of whether the script is in an xact, so maybe this'd be far harder than
it's worth. Seems like it deserves some consideration though.
