I'm about to start getting the slony-I 1.1 port ready for freebsd's  
package system.  I have a concern about the upgrade process.  In  
freebsd, the port system first removes the old package, then installs  
the new one when doing an upgrade.  What will happen to the PG  
backend if a new one is forked during the window where there is no  
slony objects installed?  I suspect it will fail to load the  
necessary objects... or is it already pre-loaded when the postmaster  
forks the child for the new connection?


I'd like to be able to support an upgrade while the system continues  
to run, particularly on the origin servers.   how does the RPM for  
redhat handle this?
