尝试将 PostgreSQL 13 实例升级到版本 16 时，我遇到了麻烦。在此之前，我顺利地从 11 升级到 13，但现在安装 16 时出现了问题。
我愿意：
sudo apt install postgresql-16
并期望随后在 中找到配置文件/etc/postgresql/16，但没有这样的文件夹。此外，pg_lsclusters仅返回版本 13。我可以执行sudo -u postgres /lib/postgresql/16/bin/initdb -D /var/lib/postgresql/16/main，这将起作用，但随后不会出现任何服务（如），并且集群仍未出现在列表中。systemctl status [email protected]
我找不到任何线索来判断原因，或者如何继续。我apt purge多次尝试安装，然后重新安装，但都无济于事。此外，我在安装 PG 15 时也有同样的经历。欢迎提出任何想法，谢谢！
作为参考，这是安装的输出：
user@server:/etc/postgresql$ sudo apt install postgresql-16
