Has PostgreSQL 9.4 official Support on a system with more than 64

The work Robert Haas did to fix the CPU locking way back when showed
significant improvements up to 64, but so far as I know.
Thanks in Advance.
Hello Javier!
Our tests shows that PG 9.4 scales well up to 60 Intel cores. I.E
pgbech -S and DB on tmpfs gave us 700 000 tps. After 60 соres s_lock is
dominating in cpu usage%. 9.5 scales way better.
