Обсуждение: why use -Ft or -Fc instead of the other on pg_dump?

I seemed to have walked into a "spirited" debate at work today, so I'm turning
to the authorities to get it resolved. Why would one choose -Ft over -Fc (or
vice-versa) when doing pg_dump? Is there truly any difference of note
(outside the formats themselves)?

Thanks

I can't really imagine any reason to choose -Ft, except wanting to do
post-processing of the dump with command-line tools.  -Ft's lack of
compression and limitations on component size are sufficient reasons
not to choose it without a specific need to.  I think it has some
other limitations too, but those are two that I recall immediately.

Excellent. Pretty much closes the debate here. Thx Tom

My rule is "never use -Ft".  I've tripped over various bugs over the years.
Indeed, I just had another example of one (from 7.4, mind) the other day.
