About v11, ISTM that the recursive function should check for symbolic
links and possibly avoid them:
sh> cd data/base
sh> ln -s .. foo
psql> SELECT * FROM pg_ls_dir_recurse('.');
ERROR: could not stat file
"./base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo/base/foo":
Too many levels of symbolic links
CONTEXT: SQL function "pg_ls_dir_recurse" statement 1
This probably means using lstat instead of (in supplement to?) stat, and
probably tell if something is a link, and if so not recurse in them.
