Trying to answer your question (I hope I understood correctly, English
is not my mother tongue)
What I do is, given a database, to COPY every table to a file, and then
pack them up in one with a zip (except this table, that's been excluded
from compression for its size and consequent compression time), so my
backup is made up by 2 files, one with "normal data" and one with the
result of COPYing this table to a file.

A question that comes while I'm writing: but pg_dump with custom format
is not using COPY with binary format?

Thanks
