Hi All,

I was comparing postgresql performance and was just curious about
performance in case i want to store the updated index tuple version on a
different page.
I was looking into the code of heapam.c, but was not able to find loop
which i should remove so that postgresql use a different buffer for updated
index tuple version.

Please guide me, about how i can achieve this.

Regards,
Rohit Goyal
