Probably the most relevant one is in storage/file/fd.c, in AllocateDir,
which is used in a lot of places, some of which do delete files: for
example the one in RemoveOldXlogFiles probably explains the pg_xlog
failures, and SlruScanDirectory explains the pg_clog failures (along
with others). I wouldn't be surprised if others like the ones in
RelationCacheInitFileRemove and RelationCacheInitFileRemoveInDir need
patching as well.
