info 07:49:50 User Deprecated: Relying on non-optimal defaults for ID generation is deprecated, and IDENTITY results in SERIAL, which is not recommended. Instead, configure identifier generation strategies explicitly through configuration. We currently recommend "SEQUENCE" for "Doctrine\DBAL\Platforms\PostgreSQLPlatform", when using DBAL 3, and "IDENTITY" when using DBAL 4, so you should probably use the following configuration before upgrading to DBAL 4, and remove it after deploying that upgrade: $configuration->setIdentityGenerationPreferences([ "Doctrine\DBAL\Platforms\PostgreSQLPlatform" => ClassMetadata::GENERATOR_TYPE_SEQUENCE, ]); (ClassMetadataFactory.php:635 called by ClassMetadataFactory.php:546, https://github.com/doctrine/orm/issues/8893, package doctrine/orm)
