Aakash, when you get a chance, could you fill in the inch-stones

Sure, http://wiki.postgresql.org/wiki/XReader updated.

Hello Andres,
The xReader design was based on the idea that it would be nice not
to cause load on the master machine, and that by proxying the WAL
stream to the HS, using synchronous replication style to write from
xReader to the HS, you could use the HS for a source for that data
with it

Maybe we should have the stylesheet watermark the dev docs pages.

Hello Tom,
I'm not sure I
get the point of logical replication that requires a physical replica as
a prerequisite.
It would be enormously
more performant for the master to be emitting logical replication
records to start with, since it already has all the right names etc
at hand at
Thanks Josh.
It is great to be introduced to the hackers community. My limited
experience here has shown me how knowledgeable and helpful the community is.
I am looking forward to doing some exciting work this summer with help from
the hackers!

Ugh. Maybe the whole idea of getting a beta out before PGCon is doomed.
Still, if we don't try for this schedule, we're looking at at least two
more weeks' slip, because we're surely not going to wrap during PGCon.
We could do it in person!
