Developers,</span><pclass="MsoNormal"><span style="font-family:"Georgia","serif";color:black">Please help with the
followingproblem. I am running PostgreSQL 9.2.3 on SUN Solaris 9. This is 64 bit system with 32G swap and 16G RAM. I

themaximum possible value is 4G. When I decrease the configuration parameters and start the instance successfully: some
