HOW TO install or use pageinspect

Hi there,

I have a 9.1 PG Server on Windows XP
The pageinspect.dll is in C:\Program Files\PostgreSQL\9.1\lib
I am postgresql user in the database (names DB_TEST).
But I cannot use the functions like
SELECT * FROM heap_page_items(get_raw_page('aTable', 0))
They does not appear in the postgreSQL catalog in the function list...
What am I missing ?

Thanks
