Description

Adds missing entries to the topology.layer table by inspecting topology constraints on tables. This function is useful for fixing up entries in topology catalog after restores of schemas with topo data.

It returns the list of entries created. Returned columns are schema_name, table_name, feature_column.

Availability: 2.3.0

Examples

SELECT CreateTopology('strk_topo');
CREATE SCHEMA strk;
CREATE TABLE strk.parcels(gid serial, parcel_id varchar(20) PRIMARY KEY, address text);
SELECT topology.AddTopoGeometryColumn('strk_topo', 'strk', 'parcels', 'topo', 'POLYGON');

 createtopology

              1
(1 row)

CREATE SCHEMA
CREATE TABLE
 addtopogeometrycolumn
-----------------------
                     1
(1 row)

This query returns no records because the feature is already registered.

SELECT *
FROM topology.Populate_Topology_Layer();

(0 rows)

Rebuild the topology layer catalog.

SELECT topology_id, layer_id,
