问题: 今天再将数据通过excel导入pgsql数据库的时候出现了中文变为问号的情况。使用的是Navicat自带的导入功能. 思路: 是excel或者pgsql的编码格式不一样, 考虑都是用utf8 解决: (1)查看EXCEL的编码格式: 选择另存为的时候选择 工具->web选项->编码格式->utf8, 重新导入一次, 发现不行还是问号. (2)查看pgs...
schema的owner默认是该schema下的所有对象的owner,但是PostgreSQL又允许用户在别人的schema下创建对象,所以一个对象可能属于两个owner,而且schema 的owner有 drop对象的权限。 对于两个owner都有drop的权限,这个我个人认为是一个BUG。 所以千万不要把自己的对象创建到别人的schema下面,那很危险。 1. 2. 3. 4. 5. ...

Can you share what you did there ? Also, while at it we should extend the function lookup to support full "method call syntax" in general, up from one-argument case so that SELECT function(a_thing, arg2, arg 2, ...) could also be called as SELECT a_thing.function(arg2, arg 2,...
