// Insert some data
await using (var cmd = new NpgsqlCommand("INSERT INTO data (some_field) VALUES (@p)", conn))
{
cmd.Parameters.AddWithValue("p", "Hello world");
await cmd.ExecuteNonQueryAsync();
}
// Retrieve all rows
await using (var cmd = new NpgsqlCommand("SELECT some_field FROM data", conn))
await using (var reader = await cmd.ExecuteReaderAsync())
{
while (await reader.ReadAsync())
Console.WriteLine(reader.GetString(0));
