the provider stores internally the datasource URI value when created and
opens a connection to the database, so changing that value after doesn't
affect the existent connection.

BTW, why would you change that value after the layer is created?
If you have a valid reason or you think this should be the right behavior,
file a ticket on trac.

Cheers.
