所以我对 PostgreSQL 真的很陌生，在过去的 3 天里，我一直坚持这一点。我需要导入一个 PostgreSQL 数据库。该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。该数据库由我授予所有可能权限的用户 postgres 导入。我还授予了该语言所有可能的特权。

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）上提供并运行良好，导入数据库没有任何问题，但仅在 Ubuntu 服务器（也是 12.04）上存在问题。

这是我不断得到的例外：

我还更新了 jdbc posgtres 连接器。我的本地机器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，但我认为这不是问题。

我不知道我还能在那里尝试什么......

这不是 Ubuntu 的问题。这是您的数据库导入的问题。您的数据库导入错误表明您缺少触发器功能。

另外我知道代码不是你的。在某种程度上，您可以用部分唯一索引替换触发器，但是您的性能会好很多。

如果代码不是您的，您将需要跟进编写它的人，了解为什么该函数不存在，但是当您这样做时，您可能需要跟进他们用这个替换触发器：

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

这将表现得更好，并且更容易维护。
