Add cost estimation of range @> and <@ operators.
The estimates are based on the existing lower bound histogram, and a new histogram of range lengths. Bump catversion, because the range length histogram now needs to be present in statistic slot kind 6, or you get an error on @> and <@ queries. (A re-ANALYZE would be enough to fix that, though) Alexander Korotkov, with some refactoring by me.
