You should enjoy one of the patches we're furiously working on then,
which is aiming at some of the administration and monitoring pieces
here. I have my own grand vision of how easy replication should be to
setup too. Visions and plans are nice, but building functional pieces
of them and delivering them to the community is what actually moves
PostgreSQL forward. So far, multiple people have done that for sync
rep, and what we're supposed to be focused on at this stage in the
development cycle is finishing the work related to the open CommitFest
item that includes that.

I find this launch into a new round of bike-shedding a bit distracting.
If you want this to be easier to use, which it's obvious to any observer
it should be because what's delivered in 9.0 is way too complicated,
please work on finding development resources to assign to that problem.
Because that's the bottleneck on simplifying things, not ideas about
what to do. I would recommend finding or assigning a developer to work
on integrating base backup in to the streaming protocol as the biggest
single thing that would improve the built-in replication. All of the
rest of the trivia about what knobs to set and such are tiny details
that make for only a minor improvement until that's taken care of.
