I've put the *BETA* source for Postgres95 up for ftp, along with a
file of diffs to make it work, with dynamic loading, for NetBSD/i386
1.0a, although I see no reason why this won't work on other
architectures. If it does work on a different port to the 386, please
keep me informed There's also a gzipped tar archive of the patched
files, if you don't feel like using patch - in which case, untar
postgres95-beta, and then untar the files archive over the top.
The files are located on:
-rw-r--r-- 1 agc 25652 May 5 02:48 postgres95-beta-netbsd-diffs
-rw-r--r-- 1 agc 35561 May 5 03:08 postgres95-beta-netbsd-files.tar.gz
-rw-r--r-- 1 agc 1793567 May 5 03:07 postgres95-beta.tgz
I've included the announcement about Postgres95 below. Remember that
this is beta software, folks. Having said that, the only diffs I had
from the regression tests were to do with timestamps, pathnames, and
usernames. I've used the directory /usr/local/postgres95 directory
for the POSTGRESDIR location - note that any Postgres 4.2 databases
are incompatible with Postgres95 ones.
Note also that you'll need gnu make for this one (see below).
Due to quota constraints on our firewalls, I'll delete the
postgres95-beta.tgz archive on Monday 8th May 1995.
Postgres is either an extended relational database, or an O-O
database, depending upon your viewpoint.
I'm working on making binary and source packages now. All feedback

> About Postgres95
> Postgres95 is a derivative of the last official release of Postgres (version
> 4.2). The code has been ansi-fied and trimmed by 25%. There are a lot of
> internal changes that improve performance and code maintainability. Postgres95
> runs about 30-50% faster on the Wisconsin Benchmark compared to v4.2. Apart
> from bug fixes, these are the major enhancements:
> * The query language POSTQUEL has been replaced with SQL (implemented in
> the server). We do not support subqueries at the moment. (However,
> subqueries can be imitated with user defined SQL functions.) Aggregates
> have been re-implemented. We also added support for GROUP BY. The libpq
> interface is still available for C programs.
> * In addition to the monitor program, we provide a new program (psql)
> which supports GNU readline.
> * We added a new front-end library, libpgtcl, that supports Tcl-based
> clients. A sample shell, pgtclsh, provides four new Tcl commands
> to interface tcl programs with the Postgres95 backend.
> * The large object interface has been overhauled. We kept Inversion large
> objects as the only mechanism for storing large objects. (This is
> not to be confused with the Inversion file system which has been
> * The instance-level rule system has been removed. Rules are still
> available as rewrite rules.
> * A short tutorial introducing regular SQL features as well as those
> of ours is distributed with the source code.
> * gmake (instead of BSD make) is used for the build. Also, Postgres95 can

> Postgres95 has been compiled and tested on Alpha (OSF 2.1, 3.0), DECStation
> (Ultrix 4.4), SPARC (SunOS 4.1.3), SPARC (Solaris 2.4), and HP 9000/700
> (HP-UX 9.0).
> The Postgres 4.2 Linux port (courtesy of Kai Petzke) has also been integrated
> into Postgres95. However, we haven't tested the port for a couple months.
> A Windows NT port is in the works. Interested party should contact the authors

> The POSTGRES project has officially ended in 1994 and the POSTGRES group
