Well, there's your problem. You think updating all those indexes is
free? It's *expensive*. Heed the manual's advice: avoid creating
indexes you are not certain you need for identifiable commonly-used
queries.
(The reason delete is fast is it doesn't have to touch the indexes ...
the necessary work is left to be done by VACUUM.)
