What - just as many idle connections as you can? You're not interesting in running queries with them?
In total I can give 250Mb of RAM to Postgresql. It should not eat more memory. This is what Im' trying to do.
It hasn't got that sort of hard limit facility. The best you can do is to limit the maximum number of connections and then restrict the various memory settings per-backend and shared. That should let you keep it in the range you want.
