The file of toc.dat (got by using the command: pg_dump -Fd ) may be need to have readability

Hi all,
When using the command "pg_dump -Fd" to backup data, I find the content of toc.dat is hard for read, just like this:
" ^@"^(at)^@^(at)DROP SEQUENCE public.test_id_seq" , So may be we should do some work to make the file "toc.dat" more readable.

Thanks,
Lin
