Question

所以我非常喜欢PostgreSQL，过去3天我一直坚持这个。我需要导入一个PostgreSQL数据库。数据库位于一个文件夹中，并具有各种.tab文件。我有PostgreSQL 9.1版本。数据库由用户postgres导入，我授予了所有可能的权限。我还授予了该语言的所有可能权限。

脚本运行的命令是：

    CREATE OR REPLACE FUNCTION unique_toplevel_corpus_name() RETURNS TRIGGER AS $$
DECLARE
        count INTEGER := 0;
BEGIN
        IF NEW.top_level = 'y' THEN
                PERFORM * FROM corpus WHERE corpus.name = NEW.name AND corpus.t$
                GET DIAGNOSTICS count = ROW_COUNT;
                IF count != 0 THEN
                        RAISE EXCEPTION 'conflicting top-level corpus found: %'$
                END IF;
        END IF;
        RETURN NEW;
END;
$$ language plpgsql;

代码不是我的。它在我的本地机器（Ubuntu 12.04）上提供并正常工作，导入数据库没有任何问题，但仅在Ubuntu服务器（也是12.04）上出现问题。

这是我不断获得的例外：

我还更新了jdbc posgtres连接器。我的本地机器，一切正常工作和服务器之间的唯一区别是我在本地机器上有java 1.7而不是1.6但我不认为这可能是问题。

我不知道我还能在那里尝试什么...

这对Ubuntu来说不是问题。这是数据库导入的问题。您的数据库导入错误表明您缺少触发器功能。

此外，我知道代码不是你的。在某种程度上，您可以使用部分唯一索引替换触发器，但是您的性能会更好。

如果代码不是你的代码，那么你需要跟进编写它的人为什么函数不在那里，但是当你这样做时，你可能想跟进他们关于用这个替换触发器：

 CREATE UNIQUE INDEX ON corpus(name) WHERE corpus.t;

这样做会更好，更容易维护。

在Ubuntu服务器上导入PostgreSQL数据库
