exit status code table?

Hi, all.

Here

http://groups.google.com/groups?selm=200111030720.fA37KmYT005641%40linda.lfix.co.uk&output=gplain

someona said
"exit status 11" in /var/log/postgres.log
*is not* a SIGSEGV

So what is it?
Where could I found an exit status code table?
I wasn't able to find it in the PostgreSQL source code, sorry.

Thank you.
