Thread: pgsql: Remove XLogFileInit() ability to unlink a pre-existing file.
Remove XLogFileInit() ability to unlink a pre-existing file. Only initdb used it. initdb refuses to operate on a non-empty directory and generally does not cope with pre-existing files of other kinds. Hence, use the opportunity to simplify. This commit has been applied as of 421484f79c0b in v15 and newer versions. This is required on stable branches of v13 and v14 to fix a regression reported by Noah Misch, introduced by 1f95181b44c8, causing spurious failures in archive recovery (neither streaming nor archive recovery) with concurrent restartpoints. The backpatched versions of the patches have been aligned on these branches by me, Noah Misch is the author. Tests have been conducted by the both of us.
