int8 is new and not very thoroughly supported yet. Probably there
just isn't support for making an index on it (Thomas?).

Ever? Yes. Before 6.4 release? Perhaps not, but I wouldn't swear to
it. We are at a bug-fixes-only stage of the release cycle, but I do not
promise there are no bugs in libpq.

Why do you care, exactly? You shouldn't need to worry whether a
library you use is changing internally, as long as the API is stable
(and I certainly hope we do not find bugs that force an API change
at this point...)
