FWIW, I'm just installing v6.5.1 on Solaris 2.5 -- and lo!  I had the
same problem, and sure enough, SHMEMMAX is 1meg, and -N 16 worked like a
charm!  So Tom, looks like you're right.  As always.

Since this was my first time compiling/installing pgsql, I've noticed a
couple of oopses (maybe mine) in the installation instructions...  Who do
I talk to to update them?  (Example: Instead of being able simply to type
"initdb" to get started, I had to specify a user with "initdb -u
postgres".  That kind of stuff.)
