The existing multi-minmax opclasses rely on "distance" function when
deciding how to build the ranges, covering all the values. In principle,
those opclasses try to minimize the lengths of ranges, i.e. maximize the
lengths of "gaps" between them.
For some data types it's hard to construct a distance function - types
like "text" or "name" generally serve as labels, and may have ordering
only. So this uses a different approach, based on the observation that
it's the outliers that "break" BRIN minmax indexes, i.e. the lowest and
highest values. So simply sort the values, keep the (K-2) extreme values
on either tail, and build a single range representing the values in the
middle. Of course, the question is whether this is actually useful, but
that's hard to judge, and it's the best we can do.

Note that sometimes tables are left around in the regression tests for
pg_upgrade, so as we can test dedicated upgrade paths for some object
types. But, here, I think you're right: this is not a table that
matters for an upgrade and the end of the test file also expects a
cleanup. So okay for me to drop this table here.
