It is pretty general use case to use --pager=less and do not look
through all rows in the output.
Before this patch after first EPIPE the output of queries will not be
printed anymore, instead it will try to finalize the output format again
and again and obviously will fail:
Code: 75. DB::ErrnoException: Cannot write to file (fd = 16), errno: 32, strerror: Broken pipe. (CANNOT_WRITE_TO_FILE_DESCRIPTOR), Stack trace (when copying this message, always include the lines below):
