tnumber_sel_internal() Selectivity tnumber_sel_internal ( PlannerInfo *  root, VariableStatData *  vardata, TBOX *  box, CachedOp  cachedOp, Oid  basetypid  ) Returns an estimate of the selectivity of the temporal search box and the operator for columns of temporal numbers. For the traditional comparison operators (<, <=, ...) we follow the approach for range types in PostgreSQL, this function computes the selectivity for <, <=, >, and >=, while the selectivity functions for = and <> are eqsel and neqsel, respectively.
