我正在尝试使用Postgresql COPY并将文件导入数据库。第一个字段是日期字段。我仍然收到错误：
Error : ERROR: invalid input syntax for type date: "2014-01-24"
CONTEXT: COPY test_darwin, line 1, column datelastmodified: "2014-01-24"
这个领域在我看来是一个完美的约会。即使我将日期从另一条记录复制到导入文件中。
这是我的代码：
COPY test_table (datelastmodified,institutioncode ,collectioncode, catalognumber, scientificname) FROM '/Users/asle/Desktop/import_test'
和我的导入文件（以制表符分隔）：
