Since there is no Right or Wrong here, the "best" option
might be to offer both:

Raise whatever is Right for Python (that is, CamelCase)

    raise PostgresSpecificError

but support catching lower case, too:

    class postgres_specific_error(PostgresSpecificError):
        pass

    try:
        something()
    except postgres_specific_error:
        print('lower case')

For the lower case one I would exactly copy what's used by
PostgreSQL itself.

Make sense ?
