populate_geometry_columns() does not add parent tables

Reported by: pcav Owned by: pramsey
Priority: medium Milestone: PostGIS 2.0.0
Component: postgis Version: 1.5.X
Keywords: Cc: strk


Inheritance is a nice PG feature:

CREATE TABLE daughter () inherits (mother);

Unfortunately, it seems that populate_geometry_columns() does not take into account parent tables, that are not added to geometry_columns, and have to be added by hand.

You have an example of this, I find it a bit hard to believe since inherited tables are no different from others and I don't recall populate_geometry_columns going out of its way to ignore these. I can see this happening if a parent table is missing the necessary constraints to determine the geometry type /srid/dimension or it's children consist of multiple kinds of geometry types.

This is a bit of a different issue and has nothing to do with inheritance. For example in my dataset, I ran populate_geometry_columns and it didn't register two of my tables (the parent and a child that is composed of polygons and multipolygons). I think this is because there is no single type that it can ascribe to the geometry type aside from GEOMETRY. It's questionable how useful that would be to register though.

You are right. Thanks for clarifying.
