Tupple statistics function

Hi,

I have written a small function that show how many tuples are dead
etc. in a specified table. Example output is:

test=# select pgstattuple('tellers');
NOTICE:  physical length: 0.02MB live tuples: 200 (0.01MB, 58.59%) dead tuples: 100 (0.00MB, 29.30%) overhead:
12.11%pgstattuple
 
-------------  29.296875
(1 row)

Shall I add this function into contrib directory?
