Postgresqlの動的SQL構文エラー

Question

私はテーブル名の配列を受け取り、各テーブルのトリガーを作成するための配列を通してループする関数を持っています。関数はコンパイルされ、エラーなしで作成されます。 私は機能を実行しよう行くとき、私は次のエラーを取得しておくと、私は私の構文が間違って何

ERRORを確認していない：

ERROR: unterminated quoted string at or near "'; 
ELSE 
    RAISE EXCEPTION ''[audit.if_modified_func] - Trigger func added as trigger for unhandled case: %, %'',TG_OP, TG_LEVEL; 
    RETURN NULL; 
END IF; 
INSERT INTO audit.Organization VALUES (audit_row.*); 
RETURN null; 
END; 
" 
LINE 53:   audit_row.statement_only = 't'; 
             ^ 

USAGE：

SELECT audit.temp_create_trigger(ARRAY['Organization']) 

ここで機能です：

CREATE OR REPLACE FUNCTION audit.temp_create_trigger(table_names character varying[])

不足している余分な引用：

--IF audit_row.changed_fields = hstore('') THEN -- missing quotes 
IF audit_row.changed_fields = hstore('''') THEN 

..... 

--RAISE EXCEPTION ''''[audit.if_modified_func] - Trigger func added as trigger for unhandled case: %%, %%'''',TG_OP, TG_LEVEL; --more quotes then needed 

RAISE EXCEPTION ''[audit.if_modified_func] - Trigger func added as trigger for unhandled case: %%, %%'',TG_OP, TG_LEVEL;
