# Simple PostgreSQL transport usage


## Prerequisites

Ensure a PostgreSQL server is running and accessible. This sample connects to `localhost` on port `54320` using the credentials in the connection string. The database named `nservicebus` must exist before running the sample.

## Running the sample

1. Start both the Sender and Receiver projects.
1. Press <kbd>c</kbd> to send a [command](/nservicebus/messaging/messages-events-commands.md), or <kbd>e</kbd> to publish an [event](/nservicebus/messaging/messages-events-commands.md), from Sender to the Receiver.
1. The Receiver handles the message.

## Code walkthrough

### Configuring the PostgreSQL transport

<!-- snippet: TransportConfiguration -->

```cs
var connectionString = "User ID=postgres;Password=mysecretpassword;Host=localhost;Port=5432;Database=nservicebus;Pooling=true;Connection Lifetime=0;Include Error Detail=true";
var routing = endpointConfiguration.UseTransport(new PostgreSqlTransport(connectionString)
{
    TransportTransactionMode = TransportTransactionMode.SendsAtomicWithReceive
});

routing.RouteToEndpoint(typeof(MyCommand), "PostgreSql.SimpleReceiver");
```
