I can try to make a self-contained test case, but right now there's a
10e6 dependancies, so it would be great if this is enough:
Here's the gmon.out file that was created after a short run of
postgres, and the output of 'gprof /usr/local/postgres/bin/postgres
gmon.out'. The data didn't make much sense to me though.
I'll try to investigate further.
