gist picksplit iteration
At this page in documentation
http://www.postgresql.org/docs/9.0/static/gist-implementation.html and under
"picksplit" the loop that iterates through entryvec->vector[] starts from 1
(since FirstOffsetNumber equals 1).
for (i = FirstOffsetNumber; i <= maxoff; i = OffsetNumberNext(i))
I would expect it to start from 0, since C arrays are 0 based.
So my question is why does this happen?

Well I don't have any good answer other than "it's the API".
Time to have a look at some contrib code and some other, maybe, like
ip4r or prefix (the former is fixed size, the later a varlena struct,
pick a good example for you).
