1) Linux doesn't track shared pages (which is not the same as shared
   memory) anymore--the field the in 'free' output is just there to
   avoid breaking software.  Use the 'ipcs' command to list shared
   memory segments--you'll find Postgres is using what you told it to
   (otherwise it woudn't start up at all).
2) The -performance list is a good place to find out why queries are
   running slowly.
