Further patch rangetypes_selfuncs.c's statistics slot management. Values in a STATISTIC_KIND_RANGE_LENGTH_HISTOGRAM slot are float8, not of the type of the column the statistics are for.
This bug is at least partly the fault of sloppy specification comments for get_attstatsslot()/free_attstatsslot(): the type OID they want is that of the stavalues entries, not of the underlying column. (I double-checked other callers and they seem to get this right.) Adjust the comments to be more correct. Per buildfarm.
