< Add columns to pg_stats to report range histogram information (Egor
Rogov, Soumyadeep Chakraborty)
I think this applies to range type and multi range type, "range
histogram information" seems not very clear to me.
So maybe:
< Add columns to pg_stats to report range-type histogram information
(Egor Rogov, Soumyadeep Chakraborty)



Display length and bounds histograms in pg_stats
< Add new COPY option "ON_ERROR ignore" to discard error rows (Damir
Belyalov, Atsushi Torikoshi, Alex Shulgin, Jian He, Jian He, Yugo
Nagata)
duplicate name.
