Обсуждение: History of PostgreSQL
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 teamof 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 commerciallysuccessful relational database servers. (Ingres Corp. was later purchased by Computer Associates.) The Ingrescode was taken by Michael Stonebraker as part of a Berkeley project to develop an object-relational database servercalled Postgres(1986-1994). The Postgres code was taken by Illustra and developed into a commercial product. (Illustrawas 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 wasmaintained by one of the graduate students, Jolly Chen, and had an active mailing list. -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

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. > > You can find more about Ingres, Postgres and Postgres'95 at > http://search.berkeley.edu/. 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. > > 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? I may have that somewhere, though the start of development was at the beginning of July, perhaps July 3rd. -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

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

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

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...:)

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. -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026
