Skip second WriteToc() call for custom-format dumps without data.
Presently, "pg_dump --format=custom" calls WriteToc() twice. The
second call updates the data offset information, which allegedly
makes parallel pg_restore significantly faster. However, if we're
not dumping any data, there are no data offsets to update, so we
can skip this step.
