Re: Multiple databases and shared_buffers

[Rakesh Kumar <dcruncher4@xxxxxxx>]

It is a business requirement that we store our clients data in separate databases. Our sales folks insist it is non negotiable. Our current technology does

support that and also maintain buffer pools for each db independently. That's why I brought this up. Personally I don't think this is a serious limitation at all.

I think this begs the question "Why do you think you need to separate the shared_buffers"?

What version of PostgreSQL are you using?

What is your O/S?

How many CPU's on your server?

How much memory?

We will be creating multiple databases in a cluster (instance). Is there any way to separate shared_buffers for each database? Looks like not since PG does not allow user created shared buffers.

you would need to run multiple instances if you feel you need that level of control over shared_buffers.
