tinstant_value_at_timestamp() bool tinstant_value_at_timestamp ( const TInstant *  inst, TimestampTz  t, Datum *  result  ) Returns the base value of the temporal value at the timestamp. Note Since the corresponding function for temporal sequences need to interpolate the value, it is necessary to return a copy of the value
