So that an auto-ANALYZE should run each 2.5-3 hours.

If it does not proceed, check that you do not have some process still doing manual maintenance or DDL on those tables, they might lock the table and kill autovacuum

(check the pg_stat_activity, and set log_autovacuum_min_duration=0 to track all job done by autovacuum)
