Log message:
    Keep the list of to-be-NOTIFYed names in a plain List palloc'd in
    TopTransactionContext, rather than using Dllist.  This simplifies and
    speeds up the code, and eliminates a former risk of coredump when
    out of memory (since the old code didn't bother to check for malloc
    failure).  It also moves us one step closer to retiring Dllist...
