>From cb41776e0a61cc83b72c4bf0ac90ce18b6a1e6ed Mon Sep 17 00:00:00 2001 From: Justin Pryzby <pryz...@telsasoft.com> Date: Sun, 8 Mar 2020 22:57:54 -0500 Subject: [PATCH v23 05/10] 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 unreasaonbly 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.
