Exactly, after posting this I discovered the relevant CVS logs for 
changes to support restartable recovery. It seems to me that perhaps a 
little more detail in the docs would be good here.

At work some folks are using pg_standby with 8.1 and while it does work 
quite well, it took me a wee while to figure out that some of the issues 
they are having are tied up with inability to continue recovery after 
restarting the database or the os!
