That would be my suggestion - run a ppc version to dump then restore
with an intel version. Maybe a startup script can detect when to do this.
Maybe this is an argument against making universal postgres binaries.

As far as upgrades that could/should be handled in the installer script.
Dump from the installed version then install the new one and restore.
That is - using Apple's installer setup.
