Actually I got it solved, I recompiled the kernel adding the options below:
options SYSVSHM
options SYSVSEM
options SYSVMSG
options SHMMAXPGS=65536
options SEMMNI=40
options SEMMNS=240
options SEMUME=40
options SEMMNU=120
And I made the following modifications to postgresql.conf:
shared_buffers = 4096
max_fsm_relations = 1024
max_fsm_pages = 16384
sort_mem = 4096
I was tthen able to increase it, I only set maxconnections to 200, because I'm using database pooling to manage connections which I'm only using 80 connections max.
Thanks.

Most likely you are out of shared memory segments that you OS allow.
If you are on Linux try to pump-up shmmax and shmall
