tlinearseq_ever_le1() static bool tlinearseq_ever_le1 ( Datum  value1, Datum  value2, Oid  basetypid, bool  lower_inc, bool  upper_inc, Datum  value  ) static Returns true if the segment of the temporal value with linear interpolation is ever less than or equal to the base value. Parameters [in] value1,value2 Input base values [in] basetypid Oid of the base type [in] lower_inc,upper_inc Upper and lower bounds of the segment [in] value Base value
