Hm. That doesn't make any sense at all, because SIGALRM is either
caught by a handler or ignored everywhere in the Postgres backend.
There is no situation where it could legitimately cause process
termination. Is it possible you are dealing with a kernel bug?
[ thinks... ] Another possibility is that you are running some
non-Postgres code that resets SIGALRM handling to default. I have
heard rumors that Perl will do that in some cases, for example.
Are you using plperl?
