In a situation where a hosting provider of some sort is providing 
PostgreSQL, they should know that parameters like SHMMAX need to be 
increased before customers can create a larger installation.  You'd expect 
they'd take care of that as part of routine server setup.  What wouldn't 
be reasonable is to expect them to tune obscure parts of the kernel just 
for your application.
