The trouble with that is that step 3 also drops anything that depends on
the extension. Doesn't work very well for data types, for instance,
since you'd lose any user-table columns of that type.
The trick that seems to work fairly well (and ought to be better
documented) is
- dump version N database
- create empty version N+1 database
- install N+1's version of each needed contrib module into new database
- restore dump, ignoring "object already exists" errors
There is a TODO to figure out some cleaner way of handling this sort
of thing ...
