Re: factorial doc bug?

> Are you saying we should remove the whole chapter below from the docs?

Actually, it may be simply that we (now) implement factorial operators
for int8, int4, and int2. Not sure what previous releases implemented,
but perhaps it is just an issue of knowing which one should be used for
the operation. If before we only had, say, int4, then the coersion code
could easily assume that it was the correct coersion.
