As long as there are no queries running, the effect will be almost nothing. If you're sure you don't need it, you can turn off autovacuum which will bring it even closer to zero. (But as long as your db is reasonably small, having autovacuum check now and then shouldn't be noticeable either). When you start putting a query load on it, it will show of course, depending on what queries you have. Depending on what you have set for shared memory, some RAM will be used for it, but it will likely get swapped out if there is no activity. //Magnus
