There is no inherent reason why the CREATE INDEX CONCURRENTLY style of
using multiple transactions makes it necessary to leave a mess behind
in the event of an error or hard crash. Is someone going to get around
to fixing the problem for CREATE INDEX CONCURRENTLY (e.g., having
extra steps to drop the useless index during recovery)? IIRC, this was
always the plan.
