You don't really know this; some operating systems (Linux in particular) does not show shared memory as in use by a process until it is accessed. It may very well have well over 1.6 GB of shared_buffers, yet not show that in VIRT. -- Álvaro Herrera <alvhe...@commandprompt.com> The PostgreSQL Company - Command Prompt, Inc.
