Вот код с вашего изображения:
using Dapper;
using Npgsql;

Dapper.DefaultTypeMap.MatchNamesWithUnderscores = true;

var connection = new NpgsqlConnection("Host=coolify.sky-server.ru;Port=8091;Username=postgres;Password=Yazurn500;Database=lazukin");

var games = connection.Query<Game>("SELECT * FROM games");

foreach (var game in games)
{
    Console.WriteLine($"{game.Id} {game.Name} minAge={game.MinAge}, genre={game.GenreId}");
}
