我需要在我的函数 updatetodoitem 中添加一个锁定参数。现在它需要 16 个参数，我需要以某种方式更改它，以便它需要第 17 个参数。现在它说“错误函数没有参数 $17”

您还需要更改此部分:

CREATE OR REPLACE FUNCTION updatetodoitem(integer, text, text, text, integer, integer, integer, date, date, character, date, date, integer, text, boolean, text)

并大概添加一个 bool 值:

CREATE OR REPLACE FUNCTION updatetodoitem(integer, text, text, text, integer, integer, integer, date, date, character, date, date, integer, text, boolean, text, boolean)
