Ah, I see it: gistrescan() is trying to preserve the per-scankey
fn_extra values to allow caching, but what it's doing does not work
if more than one scankey refers to the same consistentFn, ie, the
same index column. A bit surprising we've not seen this before,
because I think that code has been like that for awhile.
Will fix, thanks for the report!
