Well, there are two different things here. I agree that if an app
is going to use persistent connections, it should be the app's
responsibility to manage them. But a per-database, as opposed to
installation-wide, limit on number of connections seems like a
reasonable idea. Note that the limit would result in new connections
being rejected, not old ones being summarily cut.
