> POSTGRES has undergone several major releases since then. The first "demoware" system became operational in 1987 and was shown at the 1988 ACM-SIGMOD Conference. Version 1, described in The implementation of POSTGRES , was released to a few external users in June 1989. In response to a critique of the first rule system ( A commentary on the POSTGRES rules system ), the rule system was redesigned ( On Rules, Procedures, Caching and Views in Database Systems ), and Version 2 was released in June 1990 with the new rule system. Version 3 appeared in 1991 and added support for multiple storage managers, an improved query executor, and a rewritten rule system. For the most part, subsequent releases until Postgres95 (see below) focused on portability and reliability.
Your point stands, nonetheless. There are no whippersnappers present.
