With 0002-Introduce-new-WaitEventSet-API, initdb is successful, but server start leads to below problem:
LOG: database system was shut down at 2016-03-21 11:17:13 IST
LOG: MultiXact member wraparound protections are now enabled
LOG: database system is ready to accept connections
LOG: autovacuum launcher started
FATAL: failed to set up event for socket: error code 10022
LOG: statistics collector process (PID 668) exited with exit code 1
LOG: autovacuum launcher process (PID 3868) was terminated by exception 0xC0000005
HINT: See C include file "ntstatus.h" for a description of the hexadecimal value.
I haven't investigated the problem still.
