I at least feel like we have a pretty good handle on what it was intended to mean; that is, "doesn't cause semantically significant changes to pg_dump output." I do hear some skepticism as to whether that's the best definition, but it has pretty good explanatory power relative to the current state of the code, which is something. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
