Multipolygon

A collection of zero or more polygons that do not overlap.

Examples

The following example uses the GEOMETRY type to create a table, use copy to load a multipolygon into the table, and then queries the table to view the polygon:

=> CREATE TABLE multipolygon_geom (gid int, geom GEOMETRY(1000));
CREATE TABLE
=> COPY multipolygon_geom(gid, gx filler LONG VARCHAR, geom AS ST_GeomFromText(gx)) FROM stdin delimiter '|';
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself.
>>9|MULTIPOLYGON(((2 6, 2 9, 6 9, 7 7, 4 6, 2 6)),((0 0, 0 5, 1 0, 0 0)),((0 2, 2 5, 4 5, 0 2)))
>>\.
=> SELECT gid, ST_AsText(geom) FROM polygon_geom;
 gid |                                           ST_AsText
-----+----------------------------------------------------------------------------------------------
   9 | MULTIPOLYGON(((2 6, 2 9, 6 9, 7 7, 4 6, 2 6)),((0 0, 0 5, 1 0, 0 0)),((0 2, 2 5, 4 5, 0 2)))
(1 row)

The following example uses the GEOGRAPHY type to create a table, use copy to load a multipolygon into the table, and then queries the table to view the polygon:

=> CREATE TABLE multipolygon_geog (gid int, geog GEOGRAPHY(1000));
CREATE TABLE
=> COPY polygon_geog(gid, gx filler LONG VARCHAR, geog AS ST_GeographyFromText(gx)) FROM stdin delimiter '|';
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself.

>>\.
=> SELECT gid, ST_AsText(geog) FROM polygon_geog;
