There was just some discussion about that on postgis-devel. I think the
conclusion was that you would have to do the PostGIS update as a
separate step. They intend to support both 1.3.x and 1.4.x on current
versions of Postgres for some time, so in principle you could do it in
either order.

I don't think that anything in that line is going to be helpful.
What it will lead to is people mindlessly using --force (cf our
bad experiences with -i for pg_dump). If you can't give a *useful*
ie trustworthy warning/error, issuing a useless one is not a good
substitute.
