In any case, I don’t think there are other workable solutions without

The gist of the issue is hidden [anti]correlations between columns.
I like the idea of grouping columns into a custom type when an object in
the data model is defined by several properties. This approach could
help reduce the number of clauses, hide correlations within an object,
and enable the use of histogram statistics.
I'm not sure if this idea is ready to use yet, or if Postgres has
everything needed to make it work well - just note.
