In my environment which is linux on the server side and both windows and linux on the client side I have noticed that the introduction of pg_notify (with payload) makes the size of the postgres processes on the server side increase much more than before I used the notifiy calls. My server interface is a pure psm interface and I use the pg_notify inside my psm:s.
I understand that a server process connected to a client which is listening for notifies must in some way store the data sent before it is consumed by the client. By my problem is that my linux clients don't listen for any notifications. And still the corresponding postgres process on the server side seems to grow out of control (checked with ps axuw %MEM column). This is currently a big problem for me since my linux application is an embedded application with very limited resources. And yes. I must have the notfify functionality since I'm using it from my Windows clients. My postgres version is 9.04 Is this behaviour to be expected or is there a memory problem in this area? Any idea anyone? Per-Olov Esgård The information contained in this communication and any attachments may be confidential and privileged, and is for the sole use of the intended recipient(s).
