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.)
