我正在使用Schema 14.16.01并使用java api在PostgreSQL 9.6数据库上运行它。我似乎无法从api获取我的PostgreSQL中的序列数据。我从上一个问题中看到，您需要将信息级别设置为最大值，但这似乎没有帮助。我能够获得数据库的所有其他信息，但序列。
SchemaCrawlerOptions options = new SchemaCrawlerOptions();
options.setSchemaInfoLevel(SchemaInfoLevelBuilder.maximum());
options.setColumnInclusionRule(new IncludeAll());
options.setTableInclusionRule(new IncludeAll());
options.setSchemaInclusionRule(new IncludeAll());
options.setRoutineInclusionRule(new ExcludeAll());
options.setSequenceInclusionRule(new IncludeAll());
Connection con = DriverManager.getConnection("jdbc:postgresql://localhost:5432/database", "postgres", "postgres" );
SchemaCrawler crawler = new SchemaCrawler(con, new DatabaseSpecificOverrideOptions());
这是我测试的控制台输出。

您需要确保使用SchemaCrawler - PostgreSQL插件。为了以程序方式执行此操作，您需要：
SchemaCrawler Java对象时，请确保使用正确的DatabaseSpecificOverrideOptions实例，该实例将加载PostgreSQL插件。有关示例，请参阅code from SchemaCrawlerUtility。Sualeh Fatehi，SchemaCrawler
