Create Database from EDMX file in EF6 + PostGres

Question

I need to create Database (along with Schema) from EDMX file in Entity Framework 6 + PostGres. I'm using Npgsql.2.2.5.

I tried to create it using below code.

using(var ctx = new DatabaseContentEntities()){
    ctx.CreateDatabase();
}

But it was giving me an error message like

CreateDatabase is not supported by the provider

Do the Npgsql support this, if yes please Can anyone tell me how can I solve this.

Thanks in advance.
