[Qgis-user] connection to postgres

[Bernardo Rossi Doria]

hello

upgraded to  qgis 1.0 on osx leopard.

1.   I am trying to make connection to postrges Database  but it does  
not accept anymore my password.

also going to postgres PGadminIII can see the postgres DB but cannot  
connect because of the pasword.

Tried to delete the connection on both sides and create a new one
no way to connect.

I imagine that I have to remove the old password before to create a  
new one (as super user ofcourse).

Can anyone write the correct  command from the terminal?

2. my final purpose is to import in a  qgis file a postgres_postgis  
file provided on internet called  centri_abitati.sql  with data and  
borders of italian municipalities.
can any one link me to some howto?


thankyou
bernardo
