You'll need a scripting language, either within or external to the DB.
Can't do in SQL only with current postgis.

This being a frequently recurring complaint, it may be a good idea 
allowing for a configuration setting or additional arguments to make
topological operations return NULL on robustness issues rather than
throwin an exception.

I could work on that if someone is willing to sponsor the work.
