[ADMIN] Use 7.4.1's pg_dump in 7.2.4?

[Anjan Dave]

Can I use the pg_dump from 7.4.1 on 7.4.2?   I tried copying a couple of libraries that it needed, and I can copy one-by-one that it looks for, but I am not sure how many does it need in all for the new version to work…   Purpose is to dump/restore a pretty good-sized db (19GB) on 7.2.4, so I can upgrade it to 7.4.1.   Thanks, Anjan
