Well, actually the btree_gist implementation for inet is a completely
broken piece of junk: it thinks that convert_network_to_scalar is 100%
trustworthy and can be used as a substitute for the real comparison
functions, which isn't even approximately true. I'm not sure why
Teodor implemented it like that instead of using the type's real
comparison functions, but it's pretty much useless if you want the
same sort order that the type itself defines.
