Different how? I have a hard-to-pin-down intuition that your problem is
closely associated with this issue, but without details it's impossible
to say more. IIRC there were once assumptions in rtree and/or gist
about the indexable datatype being pass-by-ref and/or varlena, and I'm
not sure how much of that has been fixed.
This seems a bit far afield for pgsql-general, however. I would
suggest offering more details on -hackers. If you could post your code
for people to play with, you'd likely get answers pretty quickly.
