In _PG_init I am creating new tranche by
RequestNamedLWLockTranche("orafce", 1);

Immediately when I try to use this lock

shmem_lock = sh_mem->shmem_lock = &(GetNamedLWLockTranche("orafce"))->lock;

I got a error

ERROR: XX000: requested tranche is not registered
LOCATION: GetNamedLWLockTranche, lwlock.c:602

Because the session initialization doesn't finish, then Orafce doesn't work
