Re: Support (was: Democracy and organisation) - Mailing list pgsql-hackers

I have an slightly different perspective on this. I hope it will be a
bit useful


Background:

I'm a senior developer for a consulting firm. I too have experience
with DB/2, Oracle, Sybase, Adabase, and M$ SQL.

In the last few years of work I've been moving from the technical side
of things to be business side ( all together now: <<eewwwww> ).


I've been following PostgreSQL for a couple of years now. Absolutely
love it. I have never implemented it on a business project, though.
Not by any personal desire to use or not to use it. Usually the db
choice is out of my hands. I cannot say personally that PostgreSQL
support is amazing - ( once again, no experience at all to draw on ),
however, I've been following the lists closely enough over the last
few years that I believe the statement to be accurate. I can say that
support services from the other vendors really aren't all that
spectacular.


Perspective:

There is one factor to database choice that I haven't seen listed
here. Culpability & legal retribution. I'm not a lawyer, and don't
claim to be - so I welcome any corrections to the accuracy of the
following. Regardless of its' legal accuracy, I can vouch for the
common belief in the following thought by corporate I.T. management.


Any corporation, whether privately or publicly held, has various legal
obligations to it's shareholders. Executive officers share in both the
financial rewards of a successful company and in the legal
responsibility that the corporation has to it's shareholders.


If a catastrophic software failure results in a high percentage of
lost revenue, a corporation might be able to seek monetary
compensation from a commercial vendor. They could even be taken to
court - depending upon licensing, product descriptions, promises made
in product literature, etc. For cases like open source projects, like
PostgreSQL, there is no legal recourse available.


So - in the extreme case, if commercial Vendor V's database blows
chunks, and causes company B to loose a lot of money. If Company B can
prove that the fault lies squarely on the shoulders of Vendor V,
Company C can sue Vendor V's a** off. Executive management isn't at
fault - because they have performed due diligence and have forged a
partnership with vendor V who has a legal responsibility for the
claims of their product.


If, however, the database was PostgreSQL, then Company C has no legal
recourse. Executive management has personally taken all responsibility
for any catastrophic software failures, and therefore have put
themselves in quite a precarious situation. No one else to take the
blame but them!


Now frankly I know that the above scenario is extreme. I was rolling
my eyes while *writing* it. But the truth is that these are the kinds
of things that technical auditors would report to a Board of
Directors. There is nothing wrong with executive management choosing
to assume risk (outside of corporate politics, that is ). Many savvy
members of management realize that the real risk is quite low. Of
course, the comfort level goes way up when the database is supporting
a non-vital business process - or a process that is several steps away
from the revenue stream.


Still - imagine a database system with data and transactional volume
the size of Google. In this case the volume of updates & inserts is
much higher. Now this database is a companies' main source of revenue
( again, extreme, but we're talking examples ). Would you blame a
corporate exec if he wasn't willing to place his own personal assets
on the line by choosing PostgreSQL over Oracle?


BTW - Oracle & other commercial vendors handle these contingencies by
buying insurance policies. If the above situation had occurred and
Oracle was the vendor, then the two companies would most likely settle
out of court by dealing with the insurer. I dunno exactly how the
claims process works on such a beast, but I know that such policies
are purchased ( and you thought the annual support fee was just to
cover the support staff's salaries?). Maybe Oracle would file a claim,
an adjuster would visit Oracle's customer, etc?


Closing:

I think PostgreSQL is a great database. I haven't explored it's good
and bad points thoroughly enough to know what applications it serves
best, and where it's weakest. I do hope to use it in enough scenarios
to find out. I hope a lawyer reads this and tells me that regardless
of what management thinks is true, the above is hog-wash. Until
someone does, I can't ignore the fact that a commercial vendor has a
legal responsibility to support the claims of their product, while an
open source group does not. I think PostgreSQL specifically keeps all
of their claims legitimate and reasonable, but that doesn't change the
fact that if someone makes an honest mistake, there is nothing that
can be done *legally* to make you correct your mistake or pay for the
damage it caused.

I normally wouldn't get involved in this one, since it's the sort of

thing that turns into a flamefest.  And anyway, I'm not sure -hackers

is the place for it (hence the followup).  But as a lowly user, I

cannot let such a comment go unanswered.


I've used several commercial products of different kinds.  I've

supported various kinds of databases.  I've worked (and, in fact,

currently work) in shops with all kinds of different support

agreements, including the magic-high-availability, we'll have it in 4

hours ones.  I've had contracts for support that were up for renewal,

and ones that had been freshly signed with a six-month trial.


But I have never, _never_ had the sort of support that I get from the

PostgreSQL community and developers.  And it has been this way ever

since I started playing with PostgreSQL some time ago, when I didn't

even know how SQL worked.  I like to have commercial support, and to

be able to call on it -- we use the services of PostgreSQL, Inc.  But

you cannot beat the PostgreSQL lists, nor the support directly from

the developers and other users.  Everyone is unvarnished in their

assessments of flaws and their plans for what is actually going to get

programmed in.  And they tell you when you're doing things wrong, and

what they are.


You cannot, from _any_ commercial enterprise, no matter how much you

are willing to pay, buy that kind of service.  People find major,

showstopper bugs in the offerings of the companies you mention, and

are brushed off until some time later, when the company is good and

ready.  (I had one rep of a company I won't mention actually tell me,

"Oh, so you found that bug, eh?"  The way I found it was by

discovering a hole in my network so big that Hannibal and his

elephants could have walked through.  But the company in question did

not think it necessary to mention this little bug until people found

it.  And our NDA prevented us from mentioning it.)


Additionally, I would counsel anyone who thinks they are protected by

a large company to consider the fate of the poor Informix users these

days.  Informix was once a power-house.  It was a Safe Choice.  But if

I were an Informix user today, I'd be spending much of my days trying

to learn DB2, or whatever.  Because I would know that, sooner or

later, IBM is going to pull out the dreaded "EOL" stamp.  And I'd

have to change my platform.


The "company supported" argument might make some people in suits

comfortable, but I don't believe that they have any justification for

that comfort.  I'd rather talk to the guy who wrote the code.
