Help Needed for pgbench with retry option

Hi Guy's
I need small help on PostgreSQL testing of HA
I am trying to run pgbench but once the primary goes down and secondary comes primary , I want to know know how I can configute pgbench to retry and autoconnect the pgbench workload which I have been running to new Primary .
the idea is to test the Retry feature of pgbench if it exists .

Is pgbeach has Retry fetaure ? if yes then what is parameter for retry needs commands .

Subject: Index degradation

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?
