Back patch of Remove durable_rename_excl() - Mailing list pgsql-hackers

Hi,

I noticed that the corruption issue related to two hardlinks pointing
to the same WAL file has been fixed in the master branch up to version
16 in commit [1]. As a result, the function durable_rename_excl()
became unused and was removed in commit [2]. Since this corruption
issue is occurring in older versions, commit [1] has been backported
for versions 13 to 15 in commit [3]. However, I don't see the
backporting for commit [2]. Is there a specific reason for this? If
not, I would suggest backporting commit [2] for versions 13 to 15 as
well.
