I have gotten some dates from the old Ingres and Postgres source code. 
Interesting how old these are:

   PostgreSQL is the most advanced open-source database server.  It is
   Object-Relational(ORDBMS), and is supported by a team of Internet
   developers.  PostgreSQL began as Ingres, developed at the University
   of California at Berkeley(1977-1985).  The Ingres code was  taken and
   enhanced  by Ingres Corporation, which produced one of the first
   commercially successful relational database servers.  (Ingres Corp.
   was later purchased by Computer Associates.)  The Ingres code was
   taken by Michael Stonebraker as part of a Berkeley project to develop
   an object-relational database server called Postgres(1986-1994).  The
   Postgres code was taken by Illustra and developed into a commercial
   product.  (Illustra was later purchased by Informix and integrated
   into Informix's Universal Server.)  Several graduate students added
   SQL capabilities to Postgres, and called it Postgres95(1995).  The
   graduate students left Berkeley, but the code was maintained by one of
   the graduate students, Jolly Chen, and had an active mailing list.

 Postgres95

 In 1994, Andrew Yu and Jolly Chen added a SQL language interpreter to Postgres, and the code was
          ^^^^^^^^^
He should be mentioned as well...

 subsequently released to the Web to find its own way in the world. Postgres95 was a public-domain,
 open source descendant of this original Berkeley code.

You can find more about Ingres, Postgres and Postgres'95 at
http://search.berkeley.edu/.

BTW, what's the birthday of our project?
Andrew/Jolly stoped development ~ May 1996.
Mark, can you remember/find when you posted your historic
message to Postgres'95 mailing list?

Gee, I didn't see that.  Thanks.  The new paragraph reads:

The Postgres code was taken by Illustra and  developed into a commercial
product.  (Illustra was later purchased by Informix and integrated into
Informix's  Universal Server.)  Two Berkeley graduate students, Jolly
Chen and Andrew Yu, added SQL capabilities to  Postgres, and called it
Postgres95(1994-1995).  They left Berkeley, but Jolly continued
maintaining Postgres95,  which had an active mailing list.

I used:

	http://s2k-ftp.CS.Berkeley.EDU:8000/

Choose 'database systems'.  Also inside that tree is:

	http://db.cs.berkeley.edu/source.html

Which mentions Postgres, Postgres95, and Mariposa, and Ingres.  I have
asked him to add us to the "Other Databases" page Paul maitians.

I may have that somewhere, though the start of development was at the
beginning of July, perhaps July 3rd.

The furthest back I have is sometime in '97 ... I didn't really start
gettign into saving my 'sent-mail' logs until then :(

The oldest files in CVS is:

287027    2 -r-xr-xr-x    1 scrappy          pgsql                 585 Sep
28  1994 /usr/local/cvsroot/CVSROOT/Attic/avail-actions,v

Geez, has it been almost 4years now??

Er, can someone check any math related work that Scrappy has done?  :-)

No, your message was posted in June 1996 -:)

System time must have been messed up that day.  CVS started July 1996.

I had kept it, but somehow deleted it when going through the old
postgres95 mailing list archives.

Sorry, was going by a previous file that I had found, which was Oct '95
... will go back to sleep now...

Ah, good, I was getting worried that I'd blocked out more of my past 10
years then I thought :)  I couldn't account for the '94->96 time
frame...:)

Re: [HACKERS] History of PostgreSQL
I am still getting feedback from people on the hackers list, so I will
wait a few more days to send it to Daemon News.

On the issue of "Bazaar vs. PostgreSQL", judging from the discussion we
have had, I think that may be a good topic for a separate followup
article.
