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.

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

and, 3) not error on broken symlinks.

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.

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.

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.

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.

By the way, I raised a question about using multiple CVs
simultaneously [1]. That is, I suspect that the current CV
implementation doesn't allow us to use multiple condition variables at
the same time, because all CVs use the same PCPROC member cvWaitLink
to accommodate different waiter sets. If this assumption is correct,
we should resolve the issue before spreading more uses of CVs.

Alvaro, Kyotaro, what's our plan for this?
It seems to late to deal with this pg_usleep(1000L) for PG17.
I propose following course of action
1. Close this long-standing CF item
2. Start new thread with CV-sleep patch aimed at PG18
3. Create new entry in July CF
What do you think?
Best regards, Andrey Borodin.
