I didn't think I had proposed any such thing, although maybe I'm just
not remembering. I'm pretty confused as to what the current thread is
all about.
It seems to me that in previous discussions of Streaming Replication,
Heikki put forward the proposition that the standby server should be
able to connect to the primary and stream not only newly-generated WAL
but also, if necessary, a base backup. As I recall, he argued that
without this functionality Streaming Replication would be far too
difficult to administer for the majority of users. Assuming I'm
representing his position more or less accurately, I completely agree
with it. I don't object to providing other mechanisms as well, but if
it's not about as simple as pointing the secondary at the primary and
saying "go", it's probably more complicated than I want to mess around
with.
