Set your connections in DI:

//This service returns a MySQL database
$di->set('dbMaster', function() {
     return new \Phalcon\Db\Adapter\Pdo\Mysql(array(
        "host" => "localhost",
        "username" => "",
        "password" => "",
        "dbname" => ""
    ));
});

//This service returns a PostgreSQL database
$di->set('dbSlave', function() {
     return new \Phalcon\Db\Adapter\Pdo\Mysql(array(
        "host" => "localhost",
        "username" => "",
        "password" => "",
        "dbname" => ""
    ));
});

In your models choose the connection:

public function initialize()
{
    $this->setConnectionService('dbMaster');
    //or
    $this->setConnectionService('dbSlave');
}

Another way to do this, using the same configuration

//This service returns a MySQL database
$di->set('dbMaster', function() {
    return new \Phalcon\Db\Adapter\Pdo\Mysql(array(
        "host" => "localhost",
        "username" => "",
        "password" => "",
        "dbname" => ""
    ));
});

//This service returns a PostgreSQL database
$di->set('dbSlave', function() {
    return new \Phalcon\Db\Adapter\Pdo\Mysql(array(
         "host" => "localhost",
         "username" => "",
         "password" => "",
         "dbname" => ""
    ));
});

In your model set

public function initialize()
{
    $this->setReadConnectionService('dbSlave');
    $this->setWriteConnectionService('dbMaster');

    $this->setSource('table_name');
}

If you use transaction, remember in the injector dependency to change

$di->set('dbMaster' ....

For

$di->setShared('dbMaster'....

And the rest is the same
