In terms of maintenance, it would be nice if we are able to minimize
the code added to the pg_upgrade suite, so as it would be simple to
switch this code elsewhere if need be.

I'd imagine a couple of new routines, in the lines of:
- Dump of a database into an output file given in input, as a routine
of Cluster.pm so as it is possible to do dumps from different major
versions. Format should be defined in input.
- Restore to a database from an input file, also as a routine of
Cluster.pm, for the major version argument.
- Filter of the dumps for the contents where column ordering is
inconsistent up at restore. In a new module.
- Comparison of two dumps, with potentially filters applied to them,
with diff printed. In a new module.
