...Back in 1986, Cheryl Healy and I took on running Polaroid's corporate
systems "24 X 7" - and we worked hard to make it "24 X 7 X 365.24".
Shortly thereafter - while still working with Cheryl, Angel Vila, Chris
Boerner and I took on running Bellcore's 800 telephone network full time
also - our success was measured how few minutes/seconds there was any lost
business at all on an annual basis. (Bellcore was previously known as AT&T
Bell Laboratories.) If you made an 800 number based call from '86 to '89,
the systems I managed for Bellcore helped place that call. ... I could go
on. I've worked in the "always up"  community a long time now and have
worked with/for more corporations in this capacity than nearly anyone you
might find - mostly very large, well known companies.

My observation is that we have a real shortage of quality operating
systems today, and what few exist/remain don't enjoy much market share
because they're not based on Unix, so they're largely missing out on the
Open Source activity. What may be worse, young people who don't know any
better are sometimes told/taught not to bother with anything over five
years old as it's antiquated so they don't ever find out that things could
be better - and once were. (Example, anyone who thinks "man pages" are
great has obviously got a very limited experience from which to base their
opinion!) ... As a practical matter today we mostly have a choice of
Windows or some flavor of unix, neither of which are great. That would be
very different in my opinion if only Unix didn't have this asenine view
that the choice between a memory management strategy that kills random
processes and turning that off and accepting that your system hangs is a
reasonable choice and that spending a measily % of performance in overhead
to eliminate the problem is out of the question. Asenine, I tell you.

Meanwhile, what Operating Systems ARE _today_ reliable choices upon which
to run your Postgres datababse engine?

...BTW, McDonalds in Paris?! -smile- Just make sure you order Freedom
Fries!
