Might be discussed but not clear for the below query.

In async. streaming replication do I need to run VACUUM & ANALYZE on both master & slave as to it is bit to bit replication.
Bec, while querying on master getting below result, but slave's system table is not updated.  

select last_vacuum, last_autovacuum, last_analyze, last_autoanalyze from pg_stat_user_tables where relname like 'test';
           last_vacuum            | last_autovacuum |           last_analyze           | last_autoanalyze

Slave:

select last_vacuum, last_autovacuum, last_analyze, last_autoanalyze from pg_stat_user_tables where relname like 'test';
