Can I map "raise XXX" to some custom python exceptions? - Mailing list psycopg

Right now, I have some triggers that can raise integrity constraint violations.

And in python, I have code like this:

    try:
        cursor.execute("...")
    except dbconn.InternalError, ex:

I'm working on code that handles buying and selling physical goods.
It would be nice to have exceptions that are more relevant to that
stuff -- I mean I want exceptions like "this good is not in the
warehouse" or "this good isn't available during that window of time".

Is this possible?

How do I map database exceptions to interesting exception types in python?
