Upgrade from 7.2 to 7.4

I'm trying to avoid having to install 7.3, dump 7.2 and reload 7.3, then
install 7.4, dump 7.3 and install to 7.4 ... What's the chances of just using
the 7.4 pg_dumpall on the 7.2 database and having it work 100% ?

Also, I recall that when upgrading from 7.2 to 7.3 there was something that had
to be run to bootstrap the links between sequences and their respective tables
such that if the table was dropped the sequence would go with it. What is that
thing called? Is it included in the 7.4 tarball?
