Help Needed for pgbench with retry option

Over a period of some years, particularly in tables whose contents
periodically get swapped out entirely (i.e. lots of dead rows), indexes
slowly degrade, pushing query latency up. 

Is there a way to detect this condition short of just monitoring
statement latency, so as to know when to REINDEX / build new indexes?
