Now rebased on top of fix for my own bug report (1d09fb1f). I also changed argument handling for pg_ls_dir_recurse(). Passing '.' gave an initial path of . (of course) but then every other path begins with './' which I didn't like, since it's ambiguous with empty path, or .// or ././ ... And one could pass './' which gives different output (like ././). So I specially handled the input of '.'. Maybe the special value should be NULL instead of ''. But it looks no other system functions are currently non-strict. For pg_rewind testcase, getting the output path+filename uses a coalesce, since the rest of the test does stuff like strcmp("pg_wal"). Still waiting for feedback from a committer. -- Justin

>From fbf3b0b9671b70124582db1b40a5004b06868070 Mon Sep 17 00:00:00 2001 From: Justin Pryzby <pryz...@telsasoft.com> Date: Sun, 8 Mar 2020 22:57:54 -0500 Subject: [PATCH v21 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.
