I set the memory parameters back to their defaults, and now: it works.
I'm getting 300 and 50 with initdb. I don't recall what the output form
initdb was from previous attempts, but the .conf file always had 1000
and 100.

I have never changed anything in this file (or replaced it). I did not
even know what the shared_buffers parameter was for until I ran into
this problem.

What version of OS X are you running? I thought I replicated the
problem after upgrading to 10.2.8, but now I'm not certain I ran initdb
again (I may have just rebuilt beta 5). So possibly it could be a
difference between 10.2.6 and 10.2.8. If not, I have no clue. I'll
report back if I find anything.
