tnumber_sel_span_period() Selectivity tnumber_sel_span_period ( VariableStatData *  vardata, Span *  span, Span *  period, meosOper  oper  ) Return 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 span types in PostgreSQL, this function computes the selectivity for <, <=, >, and >=, while the selectivity functions for = and <> are eqsel and neqsel, respectively.
