What: Version 4.0 of the POSTGRES DBMS From: mer@gaia.CS.Berkeley.EDU (Jeff Meredith) Date: 16 Jul 92 04:53:17 GMT
Version 4.0 of the POSTGRES DBMS is now available for distribution. Version 4.0 provides significant advances in functionality over 3.1. General improvements in the code and some key multi-user bug fixes have resulted in a much more reliable system than we have ever previously released.
Major new features include: o Complete support for language (POSTQUEL) functions. o Handling of nested dot expressions. o Optimization of predicates with expensive functions. o Binary portals o Initial support of sets o Indices on system catalogs.
Postgres runs on Sparc I, Sparc II, Sun 4 running SunOs, and DECstations running ULTRIX >= 4.0, as well as Sequent Symmetry machines. Postgres consists of about 250,000 lines of C.
If you would like to get Postgres 4.0, you can get it in one of two ways:
(1) Anonymous FTP from postgres.berkeley.edu
cd pub get postgres-setup.me binary get postgres-v4r0.tar.Z quit
Or, if you do not have net.access, you can order a Postgres distribution tape by sending a check payable to the Regents of the University of California for $150.00 to: Postgres Project 571 Evans Hall University of California Berkeley, CA 94720.
Indicate in your accompanying letter whether you want the system on a 9-track tape at 1600 BPI, at 6250 BPI, on a cartridge tape for SUN shoeboxes (QIC 24 format), or on a TK50 DEC cartridge tape.
