Thanks for looking.
The patches are separate since the early patches are the most necessary, least
disputable parts, to allow the possibility of (say) chaging pg_ls_tmpdir()
without
changing other functions, since pg_ls_tmpdir was was original motivation behind
this whole thread.
In a recent thread, Bharath Rupireddy added pg_ls functions for the logical
dirs, but expressed a preference not to add the metadata columns. I still
think that at least "isdir" should be added to all the "ls" functions, since
it's easy to SELECT the columns you want, and a bit of a pain to write the
corresponding LATERAL query: 'dir' AS dir, pg_ls_dir(dir) AS ls,
pg_stat_file(ls) AS st. I think it would be strange if pg_ls_tmpdir() were to
return a different set of columns than the other functions, even though admins
or extensions might have created dirs or other files in those directories.
Tom pointed out that we don't have a working lstat() for windows, so then it
seems like we're not yet ready to show file "types" (we'd show the type of the
link target, which is sometimes what's wanted, but not usually what "ls" would
show), nor ready to implement recurse.
As before:

Subject: [PATCH v31 04/11] pg_ls_tmpdir to show directories and "isdir"
argument..
similar to pg_stat_file().
It's worth breaking the function's return type, since core postgres creates
"shared filesets" underneath the temp dirs, and it's unreasonable to not show
them here, and the alternative query to show them is unreasaonably complicated.
See following commit which also adds these columns to the other pg_ls_*
functions. Although I don't think it matters that they're easily UNIONed, it'd
still make great sense if they returned the same columns.

Subject: [PATCH v31 07/11] pg_ls_*dir to return all the metadata from
pg_stat_file..
..but it doesn't seem worth factoring out the common bits, since stat_file
doesn't return a name, so all the field numbers are off by one.
NOTE, the atime is now shown where the mtime used to be.
Need catversion bump

Subject: [PATCH v31 08/11] pg_stat_file and pg_ls_dir_* to use lstat()..
pg_ls_dir_* will now skip (no longer show) symbolic links, same as other
non-regular file types, as we advertize we do since 8b6d94cf6. That seems to
be the intented behavior, since irregular file types are 1) less portable; and,
2) we don't currently show a file's type except for "bool is_dir".
pg_stat_file will now 1) show metadata of links themselves, rather than their
target; and, 2) specifically, show links to directories with "is_dir=false";
and, 3) not error on broken symlinks.
