 From int-postgres-log-21-05-2024.txt:

2024-05-15 03:31:31.290 GMT [4556]: [3-1] 
db=lfm,user=superuser,app=[unknown],client=::1 LOG:  connection 
authorized: user=superuser database=lfm application_name=pg_restore

That would be the lfm database being restored.

What does the log show after that as pertains to autovacuum?
