pg_dump table schema ...

Hi,

I would like to get the structures of all my tables m4_clients, m4_contacts
etc.

Help of pg_dump says :
-t, --table=TABLE dump this table only (* for all)

I have tried a :
pg_dump -U postgres -s --table=m4_* my_database
It's not give me any result ...

Neither than : (as the help says !? or I missed understand)
pg_dump -U postgres -s --table=* my_database

It's running only if I'm doing a :
pg_dump -U postgres -s --table=m4_clients my_database

Any idea for help ?

PostgreSQL v7.3.4 used !

Thanks !

Regards,
