andunder "picksplit" the loop that iterates through entryvec->vector[] starts from 1 (since FirstOffsetNumber equals
1).<br/><div style="margin-left: 40px; font-family: courier new,monospace;">for (i = FirstOffsetNumber; i <= maxoff;
i= OffsetNumberNext(i))</div><br />I would expect it to start from 0, since C arrays are 0 based.<br />So my question
iswhy does this happen?<br />
