I still don't see where I suggested removing anything. What Heikki
suggested, and I agreed with, was adding something: integrated base
backup.

I'm still totally unclear as to what you think anyone might, at some
point in the future, propose to remove.

I think the more relevant question right now is whether the work Fujii
Masao is planning to do for 8.5 is reponsive to the following comment
from Heikki:

# IMHO, the synchronous replication isn't in such good shape, I'm
afraid. I've said
# this before, but I'm not happy with the "built from spare parts"
nature of it. You
# shouldn't have to configure an archive, file-based log shipping using rsync or
# whatever, and pg_standby. All that is in addition to the direct
connection between
# master and slave. The slave really should be able to just connect to
the master, and
# download all the WAL it needs directly. That's a huge usability
issue if left as is,
# but requires very large architectural changes to fix.
