temporal_sel_period() Selectivity temporal_sel_period ( VariableStatData *  vardata, Span *  period, meosOper  oper  ) Return an estimate of the selectivity of the search period and the operator for columns of temporal values. 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.
