The whole thing is pretty mystifying, especially the ENOSPC write
failure on what seems like it couldn't have been a full disk.

I don't think anyone asked before --- after the restore fails with the
above, does the directory $PGDATA/base/16386/ exist? Although WAL
recovery should attempt to create missing files, I think it won't
try to create missing directories.
