At least I cannot see any signal handler-related stuff in the trace, but see lots of calls to stored procedure executor instead. Although several different stack traces show completely different parts of code when signal SIGSEGV arrives, which may point to asynchronous nature of the problem. Unfortunately I've not kept all the cores I've seen. It rather looks like that in some rare circumstances Postgres is unable to properly determine end of stack condition. --
