I understand what you mean, but I think we have to provide more flexibility
or options for PostgreSQL to be used wider area in the real-world.
In my case, if many updates reduce the system performance and there is no
option,
our customer will change their DBMS from PostgreSQL to MySQL or Oracle.
If the DBAs can choose fewer options, the system performance
management(monitoring)
cost gets higher, because sometimes simple architecture causes complex
operations (or tricks) in the real applications (like performance v.s. vacuum).
It is also a part of user's TCO.
I know there is no free lunch.
However, it also means if we can pay more costs, we can get more great lunch.
Just my thought...
