Hi there, we are running a fresh Postgres 8.3 installation with a single database with about 80GB of data. After a while the whole system memory is eaten up and every operation becomes very slow. Shortly after a system reboot and even without sending queries against the database the whole system memory is consumed after some time. Are there any settings that need to be set to avoid this? Currently the default settings are used ... The system is a Suse Enterprise Linux (64bit). Kind regards Eric Bartels
