Are you sure? FWIW, the changes in reorderbuffer.c for
ReorderBufferCleanupSerializedTXNs() reduce the code readability, in
my opinion, so that's one less argument in favor of this change.
The gain in ParseConfigDirectory() is kind of cool.
pg_tzenumerate_next(), copydir(), RemoveXlogFile()
StartupReplicationSlots(), CheckPointLogicalRewriteHeap() and
RemovePgTempFilesInDir() seem fine, as well. At least these avoid
extra lstat() calls when the file type is unknown, which would be only
a limited number of users where some of the three DT_* are missing
(right?).
