btree spool function

[Teju <tejasvic(at)yahoo(dot)com>]

Hi,

I am trying to understand the function of spool
structure in btree. I understand that there are 2 of
them, one for the itups to be sorted and the other for
dead tuples.
Now, if I want to see all the itups that are loaded
into the main spool (not spool for the dead tuples),
what function should i look into and which
structure/variable holds this value? 

Thanks in advance,
TPC
