Nothing at all, really, AFAIK; just a little bit of shared memory.
On certain platforms (OS X at least) there is a penalty to oversized
max_connections because each per-backend-slot semaphore is an open file
that has to be passed down when a new backend process is forked. But
this is not true on Solaris. I doubt you'd see any difference.
