Michael Paquier 307447e6db Add information about range type stats to pg_stats_ext_exprs ... This commit adds three attributes to the system view pg_stats_ext_exprs, whose data can exist when involving a range type in an expression: range_length_histogram range_empty_frac range_bounds_histogram These statistics fields exist since 918eee0c49, and have become viewable in pg_stats later in bc3c8db8ae. This puts the definition of pg_stats_ext_exprs on par with pg_stats. This issue has showed up during the discussion about the restore of extended statistics for expressions, so as it becomes possible to query the stats data to restore from the catalogs. Having access to this data is useful on its own, without the restore part. Some documentation and some tests are added, written by me. Corey has authored the part in system_views.sql. Bump catalog version.
