Subject: finding unused indexes?

Anybody have a clever way to quickly find whether there are any unused
indexes in a PG DB? One way I have done is to take queries from the DB
log, prepend an explain to each and grep the results, but I am wondering
if there are either any index  usage stats maintained somewhere inside
Postgres or if there is a slicker/less cumbersome way of doing it. Also
indexes used by functions are hard to simulate that way.
