There shouldn't be any issues with running on large SMP machines. There 
has been some speculation that lock contention (specifically for the 
BufMgrLock) might hurt performance somewhat on machines with > 4 
processors, but I don't know to what degree. In any case, you should 
certainly be able to *use* PG; how well it will perform on a many-way 
SMP box relative to, say, Oracle, I'm not sure.
