+Type::addType('integer[]', 'Pfilsx\PostgreSQLDoctrine\DBAL\Type\IntegerArray');
+Type::addType('bigint[]', 'Pfilsx\PostgreSQLDoctrine\DBAL\Type\BigIntArray');
+Type::addType('text[]', 'Pfilsx\PostgreSQLDoctrine\DBAL\Type\TextArray');
+
+// ...
+
+$platform = $em->getConnection()->getDatabasePlatform();
