It looks like if you issue a fast shutdown during recovery, postmaster
doesn't kill bgwriter.

Seems that reaper() needs to be taught that bgwriter can be active
during consistent recovery. I'll take a look at how to do that.
BTW, the message "terminating connection ..." is a bit misleading. It's
referring to the startup process, which is hardly a connection. We have
that in CVS HEAD too, so it's not something introduced by the patch, but
seems worth changing in HS, since we then let real connections in while
startup process is still running.
