Well, I just took another careful look at the 8.4.x source code. The
only occurrence of that error string is in ProcessInterrupts() when it
sees ProcDiePending set, and so far as I can see ProcDiePending is only
set by the die() signal handler, and in postmaster child processes die()
is only used as a SIGTERM handler. So it's pretty hard to come to the
conclusion that it could be anything else.
I don't know systemtap well at all, so I can't suggest any reason why
your script might be missing SIGTERM events, but it seems that it must be.
Perhaps you can find a systemtap expert who can comment on that.
