Hi, How many files really needed for postgres ? On my Linux box I checked this by lsof and found 443 open files (and sockets) by 7 backends + 1 postmaster ? This is amazing. Do postgres really needs to keep so much open files ? I use apache+mod_perl and Apache::DBI for authent./authorization and it's not difficult to reach file table limit when running 15 httpd daemons + 15 backends. I use persistent connections, so backends will stay alive. A number of backends could grow if I use different connection string (I try to avoid this). This is my development computers and there are another bunch of processes (X, window manager etc).
