Right; that's what we did in Ubuntu, we could drop the transitional
package after the first stable release with the new infrastructure,
and all that was left was a clean packaging. :)

Great! Then I'm going to implement it.

Either is fine. Both purging the 7.4.x postgresql package (which will
remove the conffiles and data) and installing the transitional 7.5.x
package (which will move them to their new places and such) will
result in a clean system.

Indeed RC is the *only* issue here. Up-to-date installed and purged
are fine, and old-installed (7.4.x) is covered with the Conflicts: and
apt automatically upgrading.
