Question

我很难理解这个错误的含义。我使用的命令是：

psql -U postgres -d app -1 -f postgres.sql

这是错误：

 psql:postgres.sql:1879: ERROR:  current transaction is aborted, commands ignored
     until end of transaction block

ROLLBACK
psql:postgres.sql:0: WARNING:  there is no transaction in progress

不确定如何使交易正在进行中。这是我尝试导入postgresl的sql文件：http://pastebin.com/2xMGhstd

Answer 1

正如joop所解释的那样，你的SQL文件不一致。

从raffle.user_id到"user".id存在外键约束，这意味着对于raffle.user_id中的每个值，"user"中必须有一行id具有相同的值。

现在"user"中没有插入id等于1的行，但脚本会尝试在raffle中插入一行，user_id等于1。

违反外键约束导致错误。一旦PostgreSQL事务中出现错误，您所能做的就是ROLLBACK。在您这样做之前，事务中的所有语句都将因您观察到的错误而失败。

您拥有的唯一解决方案是修复数据以使其保持一致，或者通过删除外键约束来放弃一致性。

备注：选择USER之类的保留SQL关键字作为名称是个坏主意。

Answer 2

正如@joop评论的那样：你的.dmp文件已经瘫痪了，因为users表中不存在user_id = 1，但在raffle表中引用了该文件。示例：运行下一个代码段，然后取消注释该用户＃1的行并重新运行。
