\dT+ does not give elements ?

Hi:

SImple/quick (hopefully)

thedb=# \dT+

                               List of data types

Schema |       Name        |   Internal name   | Size  | Elements | Description

--------+-------------------+-------------------+-------+----------+-------------

public | one_string_rec    | one_string_rec    | tuple |          |

public | pwr_stdb_data     | pwr_stdb_data     | tuple |          |

public | pwrrec            | pwrrec            | tuple |          |

public | tree_template_rec | tree_template_rec | tuple |          |

(4 rows)

...but no "elements".  These are all record types.  How can I see the composition of one of thest data types

Thanks in Advance !
