Best alternative to set a PostgreSQL schema using PHP PDO

To set the PostgreSQL DB connection, schema parameter is not to be included

$Conn = new PDO('pgsql:host=localhost;port=5432;dbname=db', 'user', 'pass');
$result = $Conn->exec('SET search_path TO accountschema');
if ( ! $result) {
die('Failed to set schema: ' . $Conn->errorMsg());
}

Is this a good practice? Is there a better way to do this?

In order to specify the default schema you should set the search_path instead.

$Conn->exec('SET search_path TO accountschema');

You can also set the default search_path per database user and in that case the above statement becomes redundant.

ALTER USER user SET search_path TO accountschema;
