Re: minor: contrib/btree_gin/btree_gin.c uses DirectFunctionCall3(inet_in, ..)

contrib/btree_gin/btree_gin.c uses DirectFunctionCall3(inet_in,..)
instead of DirectFunctionCall1(inet_in, one_argument).

That doesn't seem right. Does such a thing matter?

It's not really incorrect: in a call going through InputFunctionCall(),
which is the normal path, the two extra arguments would be provided
whether the specific datatype input function needed them or not.

However, I think the usual convention for DirectFunctionCall() usage
is to pass exactly what the target function uses, since you know
exactly what you're calling. Certainly that's what happens in the
two direct calls to inet_in in the core code.

So I tend to agree that we should change this call to match the others,
but it's purely cosmetic.

So, are there any additional steps that you might recommend that I take?
It's such a trivial thing. I could provide a patch, of course, or a
pull request off of github if people use that.

For as much as it's worth, I did review the patch and it looks just perfect.
