.SH "DESCRIPTION"
This section describes the data types, functions and operators
several possibilities for formats, such as date and time types.
.SH "Syntax of date and time types"
-Some date and time types share code for data input. For those types (currently
-.IR datetime
-and
-.IR abstime
-, and
-.IR timespan
-and
+Most date and time types share code for data input. For those types (
+.IR datetime ,
+.IR abstime ,
+.IR timestamp ,
+.IR timespan and
.IR reltime )
the input can have any of a wide variety of styles. For numeric date representations,
European and US conventions can differ, and the proper interpretation is obtained
Valid relative times are less than or equal to 68 years.)
In addition, the special relative time \*(lqUndefined RelTime\*(rq is
provided.
+
+.SH "TIMESTAMP"
+This is currently a limited-range absolute time which closely resembles the
+.IR abstime
+data type. It shares the general input parser with the other date/time types.
+In future releases this type will absorb the capabilities of the datetime type
+and will move toward SQL92 compliance.
+
+.PP
+timestamp is specified using the same syntax as for datetime.
+
.SH "TIME RANGES"
Time ranges are specified as:
.PP
.nf
( x1 , y1 ) , ... , ( xn , yn )
.nf
- x1 , y1 , ... , xn , yn
+ ( x1 , y1 , ... , xn , yn )
.nf
-( closed, n, x1 , y1 , ... , xn , yn )
+ x1 , y1 , ... , xn , yn
.sp
where
(x1,y1),...,(xn,yn) are points 1 through n
a leading "[" indicates an open path
a leading "(" indicates a closed path
- a single leading "(" indicates a v6.0-compatible format
- closed is an integer flag which is zero for an open path
- n is the number of points in the path
.fi
.PP
Paths are output using the first syntax.
-The last format is supplied to be backward compatible with v6.0 and earlier
-path formats and will not be supported in future versions of Postgres.
+Note that Postgres versions prior to
+v6.1 used a format for paths which had a single leading parenthesis, a "closed" flag,
+an integer count of the number of points, then the list of points followed by a
+closing parenthesis. The built-in function upgradepath() is supplied to convert
+paths dumped and reloaded from pre-v6.1 databases.
+
.SH "POLYGON"
Polygons are represented by sets of points. Polygons should probably be
considered
.nf
( x1 , y1 ) , ... , ( xn , yn )
.nf
- x1 , y1 , ... , xn , yn
+ ( x1 , y1 , ... , xn , yn )
.nf
-( x1 , ... , xn , y1 , ... , yn )
+ x1 , y1 , ... , xn , yn
.sp
where
(x1,y1),...,(xn,yn) are points 1 through n
- a single leading "(" indicates a v6.0-compatible format
.fi
.PP
Polygons are output using the first syntax.
The last format is supplied to be backward compatible with v6.0 and earlier
path formats and will not be supported in future versions of Postgres.
+ a single leading "(" indicates a v6.0-compatible format
+( x1 , ... , xn , y1 , ... , yn )
+Note that Postgres versions prior to
+v6.1 used a format for polygons which had a single leading parenthesis, the list
+of x-axis coordinates, the list of y-axis coordinates, followed by a closing parenthesis.
+The built-in function upgradepoly() is supplied to convert
+polygons dumped and reloaded from pre-v6.1 databases.
+
.SH "CIRCLE"
Circles are represented by a center point and a radius.
.PP

+ datetime datetime(abstime) convert to datetime
date
datetime datetime(date) convert to datetime
datetime datetime(date,time) convert to datetime
datetime
- abstime abstime(datetime) convert to abstime
+ timespan age(datetime,datetime) date difference preserving months and years
float8 date_part(text,datetime) specified portion of date field
