This is most definitely due to the pgstat select/APC bug. See
http://archives.postgresql.org/pgsql-hackers-win32/2004-03/msg00041.php
or
http://archives.postgresql.org/pgsql-hackers/2004-03/msg00246.php
With CVS sources I can reproduce the described behaviour. With a local patch
for the above bug, the problem goes away.

That is strange. I've got it too. Looks like the extra process is the
BackgroundWriter, and it is looping forever in BufferBackgroundWriter. I'll
look into it.

No, on both counts.
