The <createTable> change works the same as before except that now columns may have a geometry type.
<changeSet id="1" author="bob">
<createTable tableName="home">
<column name="id" type="bigint">
<constraints nullable="false" primaryKey="true" primaryKeyName="home_pk" />
</column>
<column name="address" type="varchar(255)" />
<column name="location" type="geometry(Point, 4326)"/>
</createTable>
</changeSet>
