A backup generated by pg_dump never includes writes that are in flight while the backup is being taken. That would make the backup absolutely worthless!
Hmm, i kinda glossed over my point:
if you come up with your own process to chop up the backup into little pieces, you risk letting writes in, and then yeah, worthless.
