Thread: 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)?

Why would one choose -Ft over -Fc (or > vice-versa) when doing pg_dump? 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. regards, tom lane

I've tripped over various bugs over the years. Indeed, I just had another example of one (from 7.4, mind) the other day. A
