That's a timestamp without timezone range type. regards -- Tomas Vondra http://www.2ndQuadrant.com PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services

timetzrange is also missing. In my database I have:
CREATE TYPE timerange AS RANGE (SUBTYPE = time);
COMMENT ON TYPE timerange IS 'range of times without time zone';
GRANT USAGE ON TYPE timerange TO PUBLIC;
CREATE TYPE timetzrange AS RANGE (SUBTYPE = timetz);
COMMENT ON TYPE timetzrange IS 'range of times with time zone';
GRANT USAGE ON TYPE timetzrange TO PUBLIC;
The intent is that these range types are the same as if they were built in. I don't believe I have ever used timetzrange but I did it for completeness.
Given that other built-in types have built-in range types, I think that the time and timetz types should also have built-in range types.

There's only a very small number of built-in range types:
postgres=# select typname from pg_type where typtype = 'r' order by 1;
typname
-----------
daterange
int4range
int8range
numrange
tsrange
tstzrange
(6 rows)
I don't think there's any appetite for creating built-in range types
across-the-board. The time and timetz types are pretty little used
(with good reason), so leaving them out of this list seems fine to me.
