Amazon Redshift will no longer support the creation of new Python UDFs starting November 1, 2025.
If you would like to use Python UDFs, create the UDFs prior to that date.
Existing Python UDFs will continue to function as normal. For more information, see the

ST_Reverse
ST_Reverse reverses the order of the vertices for linear and areal geometries. For point or multipoint geometries, a copy of the original geometry is returned. For geometry collections, ST_Reverse reverses the order of the vertices for each of the geometries in the collection.
The dimension of the returned geometry is the same as that of the input geometry.
Syntax
ST_Reverse(geom)
Arguments
- geom
-
A value of data type
GEOMETRY
or an expression that evaluates to aGEOMETRY
type.
Return type
GEOMETRY
The spatial reference system identifier (SRID) of the returned geometry is the same as that of the input geometry.
If geom is null, then null is returned.
Examples
The following SQL reverses the order of the points in a linestring.
SELECT ST_AsEWKT(ST_Reverse(ST_GeomFromText('LINESTRING(1 0,2 0,3 0,4 0)', 4326)));
st_asewkt
------------------------------------
SRID=4326;LINESTRING(4 0,3 0,2 0,1 0)
