Support range data types. 

Selectivity estimation functions are missing for some range type operators,
which is a TODO.

<para>
Range types are data types representing a range of values over some
sub-type with a total order. For instance, ranges
of <type>timestamp</type> might be used to represent the ranges of
time that a meeting room is reserved. In this case the data type
is <type>tsrange</type> (short for "timestamp range"),
and <type>timestamp</type> is the sub-type with a total order.
</para>
<para>
Range types are useful because they represent many points in a
single value. The use of time and date ranges for scheduling
purposes is the clearest example; but price ranges, measurement
ranges from an instrument, etc., are also useful.

<title>Inclusive and Exclusive Bounds</title>
<para>
Every range has two bounds, the lower bound and the upper bound. All
points in between those values are included in the range. An
inclusive bound means that the boundary point itself is included in
the range as well, while an exclusive bound means that the boundary
point is not included in the range.
</para>
<para>
An inclusive lower bound is represented by <literal>[</literal>
while an exclusive lower bound is represented
by <literal>(</literal> (see <xref linkend="rangetypes-construct">
and <xref linkend="rangetypes-io"> below). Likewise, an inclusive
upper bound is represented by <literal>]</literal>, while an
exclusive upper bound is represented by <literal>)</literal>.
</para>
<para>
Functions <literal>lower_inc</literal>
and <literal>upper_inc</literal> test the inclusivity of the lower
and upper bounds of a range, respectively.
</para>
</sect2>
<sect2 id="rangetypes-infinite">
<title>Infinite (unbounded) Ranges</title>
<para>
The lower bound of a range can be omitted, meaning that all points
less (or equal to, if inclusive) than the upper bound are included
in the range. Likewise, if the upper bound of the range is omitted,
then all points greater than (or equal to, if omitted) the lower
bound are included in the range. If both lower and upper bounds are
omitted, all points are considered to be in the range.
</para>
<para>
Functions <literal>lower_inf</literal>
and <literal>upper_inf</literal> test the range for infinite lower
and upper bounds of a range, respectively.
</para>
</sect2>
<sect2 id="rangetypes-io">
<title>Input/Output</title>
<para>
The input follows one of the following patterns:
<synopsis>
(<replaceable>lower-bound</replaceable>,<replaceable>upper-bound</replaceable>)
(<replaceable>lower-bound</replaceable>,<replaceable>upper-bound</replaceable>]
[<replaceable>lower-bound</replaceable>,<replaceable>upper-bound</replaceable>)
[<replaceable>lower-bound</replaceable>,<replaceable>upper-bound</replaceable>]
empty
</synopsis>
Notice that the final pattern is <literal>empty</literal>, which
represents an empty range (a range that contains no points).
</para>
<para>
The <replaceable>lower-bound</replaceable> may be either a string
that is valid input for the sub-type, or omitted (to indicate no
lower bound); and <replaceable>upper-bound</replaceable> may be
either a string that is valid input for the sub-type, or omitted (to
indicate no upper bound).
</para>
<para>
Either the <replaceable>lower-bound</replaceable> or
the <replaceable>upper-bound</replaceable> may be quoted
using <literal>""</literal> (double quotation marks), which will allow
special characters such as "<literal>,</literal>". Within quotation
marks, "<literal>\</literal>" (backslash) serves as an escape
character.
</para>
<para>
The choice between the other input formats affects the inclusivity
of the bounds. See <xref linkend="rangetypes-inclusivity">.

<programlisting>
-- includes point 3, does not include point 7, and does include all points in between

accepts from zero to three arguments. The zero-argument form
constructs an empty range; the one-argument form constructs a
singleton range; the two-argument form constructs a range
in <literal>[ )</literal> form; and the three-argument form
constructs a range in a form specified by the third argument. For
example:
<programlisting>

SELECT numrange(1.0, 14.0, '(]');
-- The int4range input will exclude the lower bound and include the upper bound; but the
-- resulting output will appear in the canonical form; see <xref linkend="rangetypes-discrete">.
SELECT int8range(1, 14, '(]');
-- Single argument form constructs a singleton range; that is a range consisting of just
-- one point.
SELECT numrange(11.1);
-- Zero-argument form constructs and empty range.
SELECT numrange();
-- Using NULL for a bound causes the range to be unbounded on that side; that is, negative
-- infinity for the lower bound or positive infinity for the upper bound.
SELECT numrange(NULL,2.2);

discrete range has a sub-type with a well-defined "step";
e.g. <type>INTEGER</type> or <type>DATE</type>.
</para>
<para>
The <literal>canonical</literal> function should take an input range
value, and return an equal range value that may have a different
formatting. For instance, the integer range <literal>[1,
7]</literal> could be represented by the equal integer
range <literal>[1, 8)</literal>. The two values are equal because
there are no points within the integer domain
between <literal>7</literal> and <literal>8</literal>, so not
including the end point <literal>8</literal> is the same as
including the end point <literal>7</literal>. The canonical output
for two values that are equal, like <literal>[1, 7]</literal>
and <literal>[1, 8)</literal>, must be equal. It doesn't matter
which representation you choose to be the canonical one, as long as
two equal values with different formattings are always mapped to the
same value with the same formatting. If the canonical function is
not specified, then ranges with different formatting
(e.g. <literal>[1, 7]</literal> and <literal>[1, 8)</literal>) will
always be treated as unequal.
</para>
<para>
For types such as <type>NUMRANGE</type>, this is not possible,
because there are always points in between two
distinct <type>NUMERIC</type> values.
</para>
<para>
The built-in range
types <type>INT4RANGE</type>, <type>INT8RANGE</type>,
and <type>DATERNAGE</type> all use a canonical form that includes
the lower bound and excludes the upper bound; that is, <literal>[
)</literal>. User-defined ranges can use other conventions, however.
</para>
</sect2>
<sect2 id="rangetypes-defining">
<title>Defining New Range Types</title>
<para>
Users can define their own range types. The most common reason to do
this is to use ranges where the subtype is not among the built-in
range types, e.g. a range of type <type>FLOAT</type> (or, if the
subtype itself is a user-defined type).
</para>
<para>
For example: to define a new range type of sub-type <type>DOUBLE PRECISION</type>:
<programlisting>
CREATE TYPE FLOATRANGE AS RANGE (
SUBTYPE = DOUBLE PRECISION
);
SELECT '[1.234, 5.678]'::floatrange;
</programlisting>
Because <type>DOUBLE PRECISION</type> has no meaningful "step", we
do not define a <literal>canonical</literal>
function. See <xref linkend="SQL-CREATETYPE"> for more
information.
</para>
<para>
Defining your own range type also allows you to specify a different
operator class or collation to use (which affects the points that
fall between the range boundaries), or a different canonicalization
function.
</para>
</sect2>
<sect2 id="rangetypes-gist">
<indexterm>
<primary>range type</primary>
<secondary>gist</secondary>
</indexterm>
<title>Indexing</title>
<para>
GiST indexes can be applied to a table containing a range type. For instance:
<programlisting>
CREATE INDEX reservation_idx ON reservation USING gist (during);
</programlisting>
This index may speed up queries
involving <literal>&amp;&amp;</literal>
(overlaps), <literal>@&gt;</literal> (contains), and all the boolean
operators found in this
table: <xref linkend="range-operators-table">.
</para>
</sect2>
<sect2 id="rangetypes-constraint">
<indexterm>
<primary>range type</primary>
<secondary>exclude</secondary>
</indexterm>
<title>Constraints on Ranges</title>
<para>
While <literal>UNIQUE</literal> is a natural constraint for scalar
values, it is usually unsuitable for range types. Instead, an
exclusion constraint is often more appropriate
(see <link linkend="SQL-CREATETABLE-EXCLUDE">CREATE TABLE
... CONSTRAINT ... EXCLUDE</link>). Exclusion constraints allow the
specification of constraints such as "non-overlapping" on a range
type. For example:
<programlisting>
ALTER TABLE reservation
ADD EXCLUDE USING gist (during WITH &&);
</programlisting>
That constraint will prevent any overlapping values from existing
in the table at the same time:
<programlisting>
INSERT INTO reservation VALUES
( '[2010-01-01 11:30, 2010-01-01 13:00)' );
-- Result: INSERT 0 1
INSERT INTO reservation VALUES
( '[2010-01-01 14:45, 2010-01-01 15:45)' );
-- Result:
-- ERROR: conflicting key value violates exclusion constraint "reservation_during_excl"
-- DETAIL: Key (during)=([ 2010-01-01 14:45:00, 2010-01-01 15:45:00 )) conflicts with
-- existing key (during)=([ 2010-01-01 14:30:00, 2010-01-01 15:30:00 )).
</programlisting>
</para>
<para>
Combine range types and exclusion constraints
with <link linkend="btree-gist">btree_gist</link> for maximum
flexibility defining
constraints. After <literal>btree_gist</literal> is installed, the
following constraint will prevent overlapping ranges only if the
meeting room numbers are equal:
<programlisting>
CREATE TABLE room_reservation
(
room TEXT,
during TSRANGE,
EXCLUDE USING gist (room WITH =, during WITH &&)
);
INSERT INTO room_reservation VALUES
( '123A', '[2010-01-01 14:00, 2010-01-01 15:00)' );
-- Result: INSERT 0 1
INSERT INTO room_reservation VALUES
