Re: postgres memory management

Neil, thank you for your answer,

I thought about that possibility and it is possible since that computer has
512 MB RAM. But when I start and stop other programs like emacs the memory
is freed as soon as I stop them. As to KDE: I'm not concerned about a lack
of memory in general but I'm about to deploy an application on a server
that I hope will be running for a long time without me having to restart it
every two days because of a memory leak in some software. Anyway, I hope
you're right, I'll just try it :-)

thanks,
