Thanks for the suggestions. I was starting down the path you suggest of
creating nodes from the polygons and the ST_ConstranedDelaunayTriangles()
but I decided to post my question here first in case I was missing some
existing PostGIS goodness.
I couldn't get pprepair to build on Ubuntu 20.04.
Hey,
In the past I've used https://github.com/tudelft3d/pprepair for this kind
of data. Nowadays you can node the linework, take the
ConstranedDelaunayTriangles of it and reassign all of the triangles to
closest polygons to re-union back to simulate it.
