You need one connection per worker thread, and realistically you would only have one worker per cpu core. So how many LISTENing connections do you really need?

I never understood this point: - You have a separate schema for your procs - You define your procs in files - You write tests for your procs - You put your files into git - Then, in a transaction, you drop your old schema and deploy the new

That is not a good comparison. Blue and red are well defined as high frequency and low frequency electromagnetic radiation. Capitalism and socialism, on the other hand, are very vague terms, and I think the many discussions here prove that.

If it doesn't meet this definition, I wouldn't call it socialist. Otherwise, the word socialism would lose its meaning. California having high taxes does not make it socialist. Austria having free education does not make it social

Shouldn't that be 37%? 1-(1-0,24)*(1-0,093)*(1-0,0765)*(1-0,01) = 0,37

Today, you don't have to set up servers all the time either. But you can and that is a huge advantage. You don't need to hire a special person to constantly optimize your database server and indexes. You don't need sharding,

I simply don't believe that if you combine all improvements of the last 30 years, software, hardware and management combined are not 10x better. Where is the data that shows, that things are just different and not better? Things are di

As far as I know, the value produced by programmers per unit of time is extremely difficult if not impossible to measure. You could argue that a programmer in 2020 is not 10 times faster at writing 1990 style gui software, and maybe you are

There are many scientific fields that cannot conduct experiments, such as climate science. To say that this is not science is quite naive.

Almost every language has a killer application though. If you do machine learning, for example, Python is the obvious choice.

This is like saying: "Opinions differ substantially as to whether man-made climate change is real" . Yes, opinions differ, but when all mainstream scientists agree that deflation is bad, saying that "opinions differ"

For this reason you should always separate data and code and put them into separate schemas. In such a setup, deploying new code essentially means dropping and re-creating the code schema in a single transaction.
