Given the number of records, my first thought was either partitioning

The fewer rows are in the index, the quicker it will be to check,

that only works if the planner can figure out which partitions to use
in advance, otherwise it ends up having to scan all the partitions.

True, but then again, the proposed queries are quite straight-forward
so I don't expect that to be a problem, really.
Worth a test, if only to see if it helps.
