postgresql - 冲突 postgresql 语句与连接一起使用？

Question

我正在使用 on conflict语句进行更新插入，但出现错误:Syntax error near to line 58: ON CONFLICT (id_producto_final) DO .

查询语句为:

     Insert into table1 (id, value1, description, isactivated)
     select a.id, b.value1, c.description, d.isactivated
     from tableA as a
     left join tableB as b on b.id=a.id1
     left join tableC as c on c.id=a.id2
     left join tableD as d on d.id=a.id3
     ON CONFLICT (id) DO UPDATE SET isactivated= EXCLUDED.isactivated

它不适用于 do nothing ，所以不是excluded table错误。所以我猜测可能加入了错误源，但我什至不知道为什么。

有人能帮忙吗？

https://www.postgresql.org/docs/9.5/static/sql-insert.html

ON CONFLICT can be used to specify an alternative action to raising a unique constraint or exclusion constraint violation error. (See ON CONFLICT Clause below.)

https://www.postgresql.org/docs/9.4/static/sql-insert.html - 没有这样的选择。 ON CONFLICT从9.5开始解释

https://www.postgresql.org/docs/9.5/static/release-9-5.html

Major enhancements in PostgreSQL 9.5 include:

Allow INSERTs that would generate constraint conflicts to be turned into UPDATEs or ignored
