Wrong deprecation error from when parent::deprecatedMethod() called from trait

  Line   src/Persistence/Sql/Postgresql/PlatformTrait.php (in context of anonymous class)

  115    Call to method getCreateTableSQL() of deprecated class                            
         Doctrine\DBAL\Platforms\AbstractPlatform:                                         
         Use {@link PostgreSQLPlatform} instead.

trait is implemented in anonymous class https://github.com/atk4/data/blob/bb1c18f5dc583fca7dd372f98a0172fe66663057/src/Persistence/Sql/Connection.php#L279

thus parent::getCreateTableSQL(... call inside the trait refers to (by the phpstan error recommended) PostgreSQLPlatform class
