Wow. Okay, this is more interesting. It has some interaction with:
\set ON_ERROR_ROLLBACK 'on'
in my .psqlrc. If I remove that, then it works as expected. My
understanding of ON_ERROR_ROLLBACK is that it'll set a savepoint before
each command and then will roll back to that savepoint on an error- but
it's still all inside of one main transaction. Seems like
ON_ERROR_ROLLBACK is rolling back on a non-error in this case.. Strikes
me as very bizarre.

Try setting ON_ERROR_ROLLBACK to 'on' and doing 'set local role'...
This is on 8.2.4.

Thanks,
