[COMMITTERS] pgsql: Further patch rangetypes_selfuncs.c's statistics slotmanagement - Mailing list pgsql-committers

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.
