The reason the SHR number grows over time is that the system only counts a page of shared memory against the process after the process has first touched it. Once the bgwriter has touched every page of shared buffers, the number will stop changing. If there were actually a memory leak, the VIRT number would be growing ... but it's not. >> My postgres version is 8.1.3 If I were you, I'd be considerably more worried about the fact that you are running an old release with a pile of known bugs. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
