Tsearch Index Size and GiST vs. GIN

Due to popular demand (1 person), I've compared sizes with 90 and 100 
fillfactors, along with using the new GIN index.

Findings were not surprising, except for the GIN indexes, which doubled in 
size.

After several ALTER/RE INDEXes, here they are:

GiST
----
8.1 = 94990
8.2 FF90 = 106244 relpages (8k)
8.2 FF100 = 95049

GIN
---
FF100 = 197702
