Answer 1

You can just add a Sql("SQL COMMAND HERE") method call to your migration's Up method. Don't forget to also add the drop statement to the Down method. You can create an empty migration if you need, just by running Add-Migration without any changes to the model.

public partial class Example : DbMigration
{
    public override void Up()
    {
        Sql("CREATE OR REPLACE TRIGGER [name] BEFORE UPDATE ON myTable ...");
    }

    public override void Down()
    {
        Sql("DROP TRIGGER [name]");
    }
}
