discovering an index definition

Hi,

While "\d foo" will describe all of the fields and their
data types for the table foo, how do I do something similar
for an index?

test2=# \di i_lane_tx_tmp
       List of relations
     Name      | Type  | Owner
---------------+-------+-------
 i_lane_tx_tmp | index | me
(1 row)

This isn't enough information...

TIA,
Ron
