My thought would be that TransactionGetDeferredTriggers() ought to be
called in one place that then passes the list pointer to the other
subroutines.  I haven't looked at the code in detail to see how this
fits in ... but I don't like the notion of all these little functions
independently fetching a pointer from some nontrivial function.  That
opens you up to interesting problems if different functions manage to
fetch different results.
