Re: pg_stat_reset round 3

Interesting that all callable function must return a type. I did:

test=> select proname from pg_proc where prorettype = 0;

and none of the functions with 0 prorettype can be called from psql. I
guess boolean is the best we can do. I guess because it is a function
it has to return something.
