index support for arrays (GiST)

Hi,

we are getting a bit close to add index support for int arrays using
GiST interface. This will really drive up performance of our full text
search fully based on postgresql. We have a problem with broken index
and couldn't find a reason. I attached archive with sources
for GiST functions and test suite to show a problem - vacuum analyze
at end end of TESTSQL should complain about broken index.
Here is a short description:
1. untar in contrib 7.0.*
2. cd _intarray
3. edit Makefile for TESTDB (name of db for test)
4. createdb TESTDB
5. gmake
6. gmake install
7. psql TESTDB < TESTSQL
Regards,
    Oleg
