postgresql 更新错误ERROR： invalid input syntax for type boolean：

我正在try 对postgresql进行一个简单的更新查询.我不太理解这个错误，因为没有布尔值或列类型.

cat=> UPDATE categories SET epekcategoryid='27af8b1e-c0c9-4084-8304-256b2ae0c8b2' and epekparentcategoryid='root' WHERE categoryId='281' and siteid='0' and categoryparentid='-1';
ERROR:  invalid input syntax for type boolean: "27af8b1e-c0c9-4084-8304-256b2ae0c8b2"
LINE 1: UPDATE categories SET epekcategoryid='27af8b1e-c0c9-4084-830...

表格配置:

cat=> \d categories;
