Probably your system has a small limit on the amount of memory that can
be reserved as shared memory.  This is a tunable kernel parameter on
most of the systems I know, but I don't know the exact procedure for
changing it on SunOS --- see your sysadmin, or start reading the manuals
if you are the sysadmin...

BTW, you should consider upgrading to Postgres 6.4.
