Re: Max_connections limit

You now that Postgres don’t have any shared_pool as Oracle, and the  session information ( execution plan, etc..) are
onlyavailable for the current session. Therefore I also highly recommend to us a connection poll as Laurent wrote, in
orderto have higher chance that some stuff is already cached in the shared session available.
