[postgis-users] field type "public.geometry"

[Phil Hurvitz]

Thanks Bborie, there is something that we must be doing wrong or 
misunderstanding, or both. I assume we want all geometry columns to be 
associated with the public schema. However, there seems to be a mix.

It seems we have a geometry data type in schema gis and a geometry data 
type in schema public. When search order is changed, PostgreSQL will use 
the data type that it finds first by search order.

twins=# set search_path to public;
SET
twins=# \dT
           List of data types
  Schema |     Name      | Description
--------+---------------+-------------
  public | box2d         |
  public | box3d         |
  public | box3d_extent  |
  public | chip          |
  public | geography     |
  public | geometry      |
  public | geometry_dump |
  public | gidx          |
  public | pgis_abs      |
  public | spheroid      |

To complicate matters, it also seems that the data types in schema gis 
are from `create extension postgis', since they include the raster type 
as well.

twins=# set search_path to gis;
SET
Time: 0.085 ms
twins=# \dT
 
                    List of data types
  Schema |     Name      | 
                                    Description
--------+---------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
  gis    | box2d         | postgis type: A box composed of x min, ymin, 
xmax, ymax. Often used to return the 2d enclosing box of a geometry.
  gis    | box2df        |
  gis    | box3d         | postgis type: A box composed of x min, ymin, 
zmin, xmax, ymax, zmax. Often used to return the 3d extent of a geometry 
or collection of geometries.
  gis    | geography     | postgis type: Ellipsoidal spatial data type.
  gis    | geometry      | postgis type: Planar spatial data type.
  gis    | geometry_dump | postgis type: A spatial datatype with two 
fields - geom (holding a geometry object) and path[] (a 1-d array 
holding the position of the geometry within the dumped object.)
  gis    | geoms         |
  gis    | geomval       | postgis raster type: A spatial datatype with 
two fields - geom (holding a geometry object) and val (holding a double 
precision pixel value from a raster band).
  gis    | gidx          |
  gis    | histogram     | postgis raster type: A composite type used as 
record output of the ST_Histogram and ST_ApproxHistogram functions.
  gis    | path_result   |
  gis    | pgis_abs      |
  gis    | quantile      |
  gis    | raster        | postgis raster type: raster spatial data type.
  gis    | reclassarg    | postgis raster type: A composite type used as 
input into the ST_Reclass function defining the behavior of 
reclassification.
  gis    | spheroid      |
  gis    | summarystats  | postgis raster type: A composite type used as 
output of the ST_SummaryStats function.
  gis    | valid_detail  |
  gis    | valuecount    |
  gis    | vertex_result |

So what I think I want to do is install the updated types from the 
postgis extension to the public schema, and then drop those types from 
the gis schema. Looks like a real mess since I can't seem to cast 
geometries in one schema to geometries in another schema.

Thanks for any help anyone can suggest!
