Hmm. PG docs say:

"Moreover, ROLLBACK TO is the only way to regain control of a
transaction block that was put in aborted state by the system due to
an error, short of rolling it back completely and starting again."

which I thought implied that you can rollback to a savepoint after an
error. I'll try it out ...
