We strongly recommend using connection pooling to connect to your database because it's compatible with both IPv4 and IPv6 networks. You'll only need to change the connection credentials that you're using in your application to the pooler's connection credentials.

Since your project has the IPv4 add on, you are not required to use the connection pooler even if your network only supports IPv4.
}> Learn moreYou need to set your Pool Mode to{' '} Transaction in the{' '} Connection pooling configuration section below in order to use transaction mode on port 6543.
Otherwise, port 6543 will continue to connect in{' '} Session mode.
