The names are expected to look like this:
$ sudo find /var/lib/pgsql/12/data/base/pgsql_tmp -ls
142977 4 drwxr-x--- 3 postgres postgres 4096 Dec 27 13:51 /var/lib/pgsql/12/data/base/pgsql_tmp

I think we'd have to show sudbdir/file1, subdir/file2, not just file1, file2.
It doesn't seem useful or nice to show a bunch of files called 0.0 or 1.0.
Actually the results should be unique, either on filename or (dir,file).
"ls" wouldn't list same name twice, unless you list multiple dirs, like:
|ls a/b c/d.
It's worth thinking if subdir should be a separate column.
I'm interested to hear back from others.
