I think that we need to think long-term here and be confident in the
fact we will still see breakages with collations and glibc, using a
solution that we think is the right API. Peter's idea to make the
backend-aware command of the filtering is cool. On top of that, there
is no need to add any conflict logic in reindexdb and we can live with
restricting --jobs support for non-index objects.
