Wouldn't it be pretty easy to run postgres through a process that has a
setrlimit on the memory? I assume that postgres handles memory errors
gracefully. I think the shared memory limit combined with setrlimit would
give him what he needs.
It might be a good idea to try to run all the databases under one postmaster,
since that way you can set the shared memory higher, and all the backends
would benefit.
