is this a 64bit postgres build?
if not, you're probably running out of virtual address space in the 32
bit user space, which is limited to like 2gb.
IIRC, the virtual address space in 32bit platforms is 4GB.
it is, but within that 4gb, the kernel uses the top 1gb, so there's 3gb
left for user program space in each process. shared memory, runtime
libraries, etc all hve to come out of this 3gb user space
