I noticed in the docs for pg_standby (docs/src/sgml/pgstandby.sgml)

Hrm, AFAIK it works... Simon?
It works, yes. But in basic form only.
You'll have problems stopping and starting standby, but the most
important change is that the process is not restartable. So if you run
it for a month and then crash, you'll need to re-run the whole month's
WAL data.
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!
Best wishes
