Change the user to connect to postgresql

[edwin-agudelo]

Hello.
I'm trying to use Phalcon just to connect to a database and select the info in a table and bring it as JSON. I configure the connection but is currently launching an error related with the authentication, but the user showed in the message is not the user that I configured in the script:
[ERROR] Error On Querying: PDOException: SQLSTATE[08006] [7] FATAL: password authentication failed for user "SYSTEM" in C:\php\app\config\di.php:49 Stack trace: #0 [internal function]: PDO->__construct('pgsql:host=192....', 'phpuser', 'phpuser', Array) #1 [internal function]: Phalcon\Db\Adapter\Pdo\AbstractPdo->connect(Array) #2 [internal function]: Phalcon\Db\Adapter\Pdo\Postgresql->connect(Array) #3 [internal function]: Phalcon\Db\Adapter\Pdo\AbstractPdo->__construct(Array) #4 [internal function]: Phalcon\Db\Adapter\Pdo\Postgresql->__construct(Array)
The code that I used to configure the application is:

return new \Phalcon\Config\Config( [ 'database' => [ 'adapter' => 'Postgresql', 'host' => '192.168.20.201', 'port' => 5432, 'username' => 'phpuser', 'password' => 'phpuser', 'dbname ' => 'solumekd', 'schema' => 'referencia', ], 'application' => [ 'controllersDir' => 'app/controllers/', 'modelsDir' => 'app/models/', 'baseUri' => '/', ], ] );

and the connection is made by:
$di->set( 'db', function() use( $config ) { return (new PdoFactory())->newInstance( 'postgresql', [ 'host' => $config->database->host, 'username' => $config->database->username, 'password' => $config->database->password, 'dbname' => $config->database->dbname, ] ); } );

As can see: the user is 'phpuser' but the error reported is from the user "SYSTEM". I'm was trying to fix in different ways, but I'm really lost.

My current environment is:

• PHP Version 8.1.10
• Phalcon 5.0.3
• PostgreSQL (libpq) Version 11.4

Please let me know if someone could help me.
