Detailed index predicate with \d on indexes in psql

(This is using 7.2b1)

Anyone know why I am getting the "internal form" of the
partial-index predicate? In other words, instead of
getting something like this (thanks Tom):

regression=# \d apple
Index "apple"
Column | Type
- ---------+---------
topping | integer
hash
Index predicate: (topping > 99)

I get something like this:

Index "apple"
Column | Type
- ---------+---------
topping | integer
hash for table "pizza" WHERE (topping > 2000)
Index predicate: ({ EXPR :typeOid 16 :opType op :oper { OPER :opno 521 :opid 14
7 :opresulttype 16 } :args ({ VAR :varno 1 :varattno 3 :vartype 23 :vartypmod -1
:varlevelsup 0 :varnoold 1 :varoattno 3} { CONST :consttype 23 :constlen 4 :co
nstbyval true :constisnull false :constvalue 4 [ 99 0 0 0 ] })})

Doing a:

SELECT c.relname, i.indpred
FROM pg_index i, pg_class c
WHERE c.oid = i.indexrelid
and i.indpred like '(%'

reveals that this is happening to every partial index I
create.

I'm also wondering if we even need the "Index predicate:"
section at all? When it works properly, will it ever give
more information than what the tail end of pg_get_indexdef
returns? If it gives the same, is one preferred over the other?

Thanks,
