Re: list of extended statistics on psql

+1 for the general idea, and +1 for \dX being the syntax to use

IMO the per-type columns should show both the type being enabled as
well as it being built.

(How many more stat types do we expect -- Tomas?  I wonder if having one
column per type is going to scale in the long run.)

Also, the stat obj name column should be first, followed by a single
column listing both table and columns that it applies to.  Keep in mind
that in the future we might want to add stats that cross multiple tables
-- that's why the CREATE syntax is the way it is.  So we should give
room for that in psql's display too.
