No. Fujii-san is saying that he will address it, if the fix made in
this thread is found to be imperfect later.
He suspects that WAL files should be preserved at least in certain
cases even if the file persists forever, but the consensus here is to
remove files under certain conditions so as not to no WAL file
persists in pg_wal directory.
Feel free to propose the next version!
