This paper suggests modifications to the POSTGRES rules system (PRS) to increase its usability and function. Specifically, we suggest changing the rule syntax to a more powerful one and propose additional keywords, introduce the notion of rulesets whose purpose is to increase the user's control over the rule activation process, and expand the versioning facility to support a broader range of applications than is currently possible.
