Isn't this also a very strong argument for putting your caching
into your application and not at the database level?
As you say the more "application or domain specific" it is the better.
I don't see how PostgreSQL is going to magically determine what
is perfect for everyone's differing needs and implement it for you.
Even rudimentary controls such "always keep this
table/index/whatever in RAM" aren't as fine grained or specific
enough to get full benefit.
My suggestion is to use something like memcached to store your
data in, based on the particular needs of your application. This
puts all of the control in the hands of the programmer where, in
my opinion, it belongs.
Just to clarify, I'm not entirely against the idea, but I certainly
think there are other areas of PostgreSQL we should be focusing our
efforts.
