The reason would be "by design." If the server flushes its cache every time the application restarts, the cache isn't going to be very effective. If PostgreSQL is using more shared buffers than you're comfortable with, reduce the shared_buffers setting in the config. That will allow the OS to decide how to use the memory instead. -- Bill Moran http://www.potentialtech.com
