--- This function has been obsoleted for the difficulty in
--- finding attribute on which the constraint is applied.
--- AddGeometryColumn will name the constraints in a meaningful
--- way, but nobody can rely on it since old postgis versions did
--- not do that.
+-- This function renames geometrytype and srid constraints
+-- applied to spatial tables by old AddGeometryColumn to
+-- new meaningful name 'enforce_geotype_<geomcolname>'

+-- Needs to be called only when upgrading from postgis < 0.8.3
