Answer 1

Installing the npgsql extension as described in tsChan's answer wasn't enough for me, I also had to modify my app.config (I suspect because it was created before I installed the extension) to include the npgsql data provider in the EntityFramework section as follows:

<entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />      
      <provider invariantName="Npgsql" type="Npgsql.NpgsqlServices, EntityFramework6.Npgsql" />
    </providers>
  </entityFramework>

After I did that, the provider appeared in the wizard options.
