async replication code

Greetings,

I am new here. Apologetic question: how can i search the archives of this
mailing list? Is there some set of magic words to put in Google? Must I
wade through 20 pages of hits? Should I download all the archives and grep?
:)

Main question: I want to understand very precisely the exact algirithm
used in PG to do asynchronous streaming replication. Eg, I want to know how
the record is written and flushed to the socket and how that happens in
time w.r.t WAL-to-disk and response to client. Will someone please give me
a head start as to where to begin my code-spelunking?
