8.4.what exactly?

Hmm.  I'm thinking that the postmaster must have simply crashed at some
time between starting the logger subprocess and starting the startup
subprocess.  You could try running the postmaster under gdb to see
if you can get a stack trace, along the lines of

    $ gdb /usr/bin/postgres
    gdb> run -d 3 -D /data/postgres/
    ... crash
    gdb> bt
    ... printout
    gdb> quit

You might need to "continue" if it decides to stop at the point of
forking off the logger.
