That is not communism. That is market economy, lesson 4.
In perfect competition the price of ONE good is exactly as high as it's marginal costs.
"marinal costs" = what does THE ADDITIONAL UNIT cost.
And for all practical purposes: Changing "you get 2000 licenses of XXX" to "you get 2001 licenses o XXX" costs zero money units.
Don't believe that "fixed cost distribution" bullshit. That is correct, but has nothing to do with market prices. In the short run, fixed costs are irrelevant for decisions, in the long run, there are no fixed costs.

Using void* or discriminated unions in C to "hold anything" is a form of dynamic typing. Templates were added to C++ precisely because this approach sucked so much.
there is quite a difference between using "void*" for everything and dynamic typing:
with void the programmer is responsible for checking if the data coming in is of correct type. with dynamice typing it's job of the runtime engine.
That is quite similiar to "templates", which have to be constructed to "adopt" to different types. And templates are very complicated - as the release of a complete book dealing with them proofes.

I'm a strong suporter of free market. I believe that there should be no restrictions on international trade, goverments should not try to compete with free enterprise. Subsidies are bad.
It is perfectly normal for government agencies to buy cars, software, toilett-paper.
Now the economic calculation:
closed source:
government has the benefit of using the software.
software-seller has the benefit of the revenue
open source / free software:
government has the benefit of using the software
software-seller has the benefit of the revenue.
public has the benefit of using the software (=public good, meritorial good).
We should assume that the benefit for government and software-seller is identical when doing the transaction with closed source and when doing the transaction with open source.
So the whole economy is on the plus, as long as the benefit of the public of using the software is > 0
since 7.2 there is an analyze without vacuuming. That is a lot faster... not the automatic update of statistics we both would prefer, but a good step forward. Since it is not locking, there is no big penalaty to do it regular
"try an insert if it fails do an update" - I miss the oracle "create or replace" command for tables - and an "update or insert"-clause would also be fine. How did you "rewrite" your procedure? Perhaps with a function "test for keyexistence if true update else insert"?
Did you test this "in-Clause" lately? I ran into that problem also with 7.1.2, solution was "select * from table1 where exist (select id from table2 where table2.id=table1.id and code = 'BLAP') - I'm not sure, but I think this "bug" in the query generator has been solved with 7.1.3 / 7.2.

Stick with MySQL when performance is critical and you want to do straight SELECTs from simple tables with few joins and very few updates
"Postgresql is slow" is a very popular myth and urban legend.
It even was a true myth - with older versions of Postgresql. Since 7.1.3 big improvements in the query-optimizer gave Postgresql big speed improvements - without stripping any of it's features.
The long time maintainance of an "old" kernel is a very important argument in favour of linux for serious industrial applications.
