tsegment_value_at_timestamp() Datum tsegment_value_at_timestamp ( const TInstant *  inst1, const TInstant *  inst2, bool  linear, TimestampTz  t  ) Return the base value of the segment of a temporal sequence at a timestamp. Parameters [in] inst1,inst2 Temporal instants defining the segment [in] linear True if the segment has linear interpolation [in] t Timestamp Precondition The timestamp t satisfies inst1->t <= t <= inst2->t Note The function creates a new value that must be freed
