Replication docs update

Our chapter, "Comparison of Different Solutions", needs an update to use
our new streaming replication terminology, and an update to mention the
synchronous option.

Patch attached.  I would like to apply it to head and 9.1.

Is it really a good idea to remove the name "hot standby" where you've
done so? It's a term that's pretty well set by now. Maybe instad "hot
standby using transaction log replication" instead of taking it away
completely?

(And i'm sure Thom will find a bunch of typos, but there is no way
around that I think..)

Well, hot/warm standby is really a side-feature of replication, not a
replication technology itself. WAL streaming is a replication
technology. For example, Shared Disk Failover is technically a warm
standby too.

True. I'm just saying it's a term that many are familiar with, and
thus removing it doesn't entirely help. Removing PITR is a good idea
however :-)

Pretty sure Shared Disk qualifies as cold standby.

Well, the term doesn't help describe what it is, so familiar doesn't
help us much.

Why is it cold? It can start up right away. What does warm mean then?
