因此，我真的是PostgreSQL的新手，在過去的3天裏，我一直堅持使用它。我需要導入一個PostgreSQL數據庫。數據庫位於一個文件夾中，並具有各種.tab文件。 我有PostgreSQL 9.1版本。數據庫由用戶postgres導入，我向其授予所有可能的特權。我也授予語言的所有可能的特權。在Ubuntu服務器上導入PostgreSQL數據庫
由腳本運行的命令是：
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;
的代碼是不是我的。它在我的本地機器（Ubuntu 12.04）上提供並正常工作，導入數據庫沒有任何問題，但僅在Ubuntu服務器（也是12.04）上出現問題。
這是我不斷收到異常：

我也更新JDBC posgtres連接器。我的本地機器的一切正常工作和服務器之間的唯一區別是，我在本地機器上安裝了java 1.7，而不是1.6，但我不認爲這可能是問題所在。
我不知道還有什麼我可以在那裏試試...
