If you are not getting the kind of support with premium or enterprise support, you better talk to your TAM. We run into problems with Redshift all the time and they are quite responsive (well they do violate their SLA often and we are too nice to deal with that right now). But of course you can't get a hold of the developers until support can't do anything else.
