Still your contention was that autovacuum quit running after the initial
restore and that is not the case. Assuming this is the instance you
restored on May 2 2024 then approximate counts are:

autovacuum_count 1888/13 days = 145 autovacuums/day = 6/hour

autoanalyze_count 1715/13 = 132 autoanalyze/day = 5.5/hr
