Oh, an old patch resurrected from the dead... Reading again the patch

+    * Increase number of initilized slots if we didn't reuse a previously
+    * used one.
s/initilized/initialized

+       Number of backends attached to this segment (1 signals a moribund
+       entry, 2 signals one user, ...).
moribund? Or target for removal.

REVOKE ALL .. FROM PUBLIC;
REVOKE EXECUTE .. ON FUNCTION FROM PUBLIC;
Revoking he execution of those views and their underlying functions
would be a good thing I think, this can give hints on the system
activity, particularly for DSM segments.
