Given that the call site is SIInsertDataEntry, it's clear that
SendPostmasterSignal is actually being told PMSIGNAL_WAKEN_CHILDREN ...
the gdb traceback is reporting the wrong value for the parameter, which
is no big surprise for values in registers.
Which makes this a perfectly normal event; it's just trying to flush the
SI messaging queue before it overflows. Nothing to see here, move
along.
