I'm thinking we should split PageGetTempPage into two versions:
PageGetTempPage: get a temp page the same size as the given page,
but don't initialize its contents at all (so, just a thin wrapper
for palloc). This could be used by _bt_split, as well as
GinPageGetCopyPage and GistPageGetCopyPage.
PageGetTempPageCopySpecial: get a temp page, PageInit it, and
copy the special space from the given page. The only customer
for this is gistplacetopage(), so maybe we don't even want it,
rather than just doing the work right in gistplacetopage()?
You could also make an argument for PageGetTempPageCopy() which'd just
copy the source page verbatim, thus replacing GinPageGetCopyPage and
GistPageGetCopyPage.
Sounds good I will look on it.
