I would like to add that there is a good reason why they aren't in the
same league. As a rule of thumb one can say that the smaller a software
company, the faster some development must turn into revenue. That is why
Oracle and Microsoft have the "time" to do things right. They can throw
20 manyears at a project and if it turns out that wasn't enough, double
down on that. I include MS on purpose here, because they gain that time
from some products, and then use it on others like SQL server. MySQL on
the other hand didn't have that "time" in the past, and look what they
do as soon as they have 19.5 million seconds more "time" ... the only
thing that is right, replace the whole architecture, or what is that
MaxSQL move? I hope 19.5 million seconds are enough, honestly. Because
nobody will double down in their case.

PostgreSQL does not have that problem because the base project itself
does not depend on any companies success. Time is relative. Our time is
very patient compared to their time. PostgreSQL gets the time it needs
for free.
