AFAICS, we do not have any category like system triggers. So yeah, it would have been nice to generate triggers with names (starting with __ for example) for such special triggers. But I don't think we disallow user-triggers starting with underscores etc. So some of the options could be: - to add a new column in pg_trigger to indicate special or system triggers which can be executed last (sorted order if multiple entries) or - invent a prefix "__partition__" or something and disallow user triggers to use such a prefix for their names, plus introduce logic to execute them (again sorted order if multiple entries) last.
