Has PostgreSQL 9.4 official Support on a system with more than 64 legitimate cores? ( 72 Cores , 4 CPUs Intel(R) Xeon(R) CPU E7-8890 )



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.
