The docs seem a little sketchy but the source implies that there is
a difference between new and old style triggers. I can't seem to find
this difference. I tried following the only current example I could
find but I get a core dump. Here is the backtrace.

It gets to fmgr_oldstyle() and then dies from a jump to a null pointer.
Can someone please tell me how to make my function a newstyle one. I
will update the docs once I have it working.
