You can use the Find Identical (Data Management) tool to find duplicate features or records. Reports any records in a feature class or table that have identical values in a list of fields, and generates a table listing these identical records. If the field Shape is selected, feature geometries are compared. The Delete Identical tool can be ...

Here is a link to my PL/pgSQL function which does exactly what the OP is asking for: removing spikes from polygons and linestrings. Here you can download it and read the documentation: PostGIS NormalizeGeometry. As suggested in the comments, here is an example: WITH temp (wkt) AS ( VALUES ('LINESTRING(0 0, 2 2, 0 4, -5 4, 0 4.001, 2 6)'), ...

You can think about postgis topology as a "container" and you can't "force" it to be a LINESTRING. You choose the geometry type of topo-geometries at "topology level" as you you did with AddTopoGeometryColumn. (the 'test' column created is LINESTRING) At the "physical level" of the topology, node table geometries are always points and edge_data table ...
