Display length and bounds histograms in pg_stats
Values corresponding to STATISTIC_KIND_RANGE_LENGTH_HISTOGRAM and
STATISTIC_KIND_BOUNDS_HISTOGRAM were not exposed to pg_stats when these
slot kinds were introduced in 918eee0c49.
This commit adds the missing fields to pg_stats.
Catversion is bumped.
