数据库用户“postgres”不是安装用户

Question

我正在尝试将postgres从9.5升级到9.6。 brew upgrade postgresql成功，但在运行时

pg_upgrade -b /usr/local/Cellar/postgresql/9.5.3/bin/ -B /usr/local/Cellar/postgresql/9.6.1/bin/ -d /usr/local/var/postgres -D /usr/local/var/postgres9.6 -U postgres

我收到错误

Performing Consistency Checks

Checking cluster versions                                   ok
Checking database user is the install user
database user "postgres" is not the install user
Failure, exiting

最后在没有-U postgres的情况下进行尝试时，它会变得更奇怪

那怎么来

Checking database user is the install user                  ok

Answer 1

旧的PostgreSQL集群显然是用

创建的

byte[] originalBytes = ...
String string = new BigInteger(originalBytes).toString();
...
byte[] decodedBytes = new BigInteger(string).toByteArray();

但新群集与另一个超级用户进行了联系。

您必须使用与旧群集相同的超级用户名创建新群集。

Answer 2

我得到这个是因为目标数据库包含一个额外的用户。

这以前是我安装和升级初始化脚本的一部分。我从升级 initdb 中删除了它，升级成功完成。
