-------------------------+-----------------------------
 It is sometimes useful to cleanup the topology by removing unused
 primitives (edges not binding areal TopoGeometries, nodes not binding
 lineal TopoGeometries).

 This is for example implemented in QGIS PostGIS Topology Editor plugin:
 https://plugins.qgis.org/plugins/pgtopoeditor/

 And is implemented in NIBIO's topo_update extension:
 https://gitlab.com/nibioopensource/pgtopo_update_sql/-/blob/910da58a375ae9454634538b6fa110167f655c41/src/sql/topo_update/function_02_cleanup_topology.sql

 This ticket is to expose such a function in core PostGIS Topology for
 reuse by others.

 See also #5180 for exposing a part of this function but specifically for
 edges only
