You mean 512 concurrent connections?  It sounds to me like you are
running into kernel-level limits on amount of shared memory or number
of semaphores.  But without seeing the error message the postmaster
puts out, it's hard to be sure.  See the discussion about "Managing
Kernel Resources" in the PG Administrator's Guide.

There has been no compile-time limit on number of connections for
several releases now, so I doubt you need to recompile.  (If you do,
you are overdue for an update.)
