It is the issue that the target file is changed but the 'pg_recvlogical'
process doesn't know it at all. So it streams all wal changes but writes
down nothing at last.

So I think we can recreate or reopen the changed file when there be
something wrong with the target file. And we can choose to kill the
'pg_recvlogical' process because it's no use at all now, or we should
give a warning to users at lease.
