3. What's the best thing to do when I deliberately shut down

pg_xlog.
Yeah, you should archive the latest WAL file, but in 8.0 you'd have to
do that manually. (IIRC there isn't even a forced-xlog-switch
function
in that version to help you.)
So in 8.2, when I do a backup I *don't* need to manually copy any WAL
files?, and when I shut down I should:
1 call pg_switch_xlog()
2 wait for the WAL to be archived *if* pg_switch_xlog return a
location after the end of the previously archived WAL
3 actually call pg_ctl stop
Do I need to do 2, above, or can postgres wait until the previous WAL
archive is complete?
Thanks,
Tom
