However you might want to check the last 4 code segments in the post. They don’t execute cleanly and they appear mixed up, for example (and I copy paste from your post):

Finally, getting the list of orphaned files:
“`
postgres=# select * from pg_ls_dir ( ‘/u02/pgdata/12/base/12724’ ) as file where file ~ ‘^[0-9]*
“`
