Hello all,

Now I'm trying to realize index in GiST. Everything is Ok, but I would like
to know about advanced index programming options.
1) For example - can I delete entry in my picksplit procedure ?
2) Or to add logical conditions - when picksplit node ? For exampe change
default "when number of entries of node is much than XX, split node" - to
"when number of entries which element "state" is "on" is much than XX, split
node ?"

Faithfully,
Sergej
