Besides being redundant, I find this hard to read in some situations because it's then very hard to tell what is different between different cases or branches.  The attached patch cleans up most of that.  I left alone instances where there are (nontrivial) comments attached to the initializations or where there appeared to be some value in maintaining symmetry.  But a lot of it was just plain useless code, some clearly copy-and-pasted repeatedly.

I personally sort of like the initializations of Lists like the one below, even
if redundant, since they then clearly stand out as being Lists.

-	fk_trigger->args = NIL;

Just a matter of personal preference, but I find that those aid readability.
