This tutorial will also use Express.js, because it makes working with Node so simple. Sequelize fits beautifully over Postgres, MSSql, MySql, and MariaDB with no need to rewrite code. To connect the two you will use an ORM (Object-Relational Mapper) called Sequelize, available via the Node Package Manager, npmjs. In this post, we will build a small application that keeps track of a To-Do List and the status of tasks, all built on Node and Postgres. The two technologies partner well as a foundation for modern, microservices-based applications. PostgreSQL has also risen in popularity, to compete with MySql. It is one of the fastest-growing and best-supported javascript frameworks available today, and its microservice patterns has made it a hit for modern enterprise applications. Now you can install pgAdmin or use your own program (in 'normal' Windows) to confirm that you can connect on 127.0.0.1 with port 5432 (may vary) with the user postgres and his boasts high performance and scalability for web, mobile, or desktop applications. Notice that the password you created is not the DB password for postgres, so unless you create a new user you can give postgres one in the psql shell: ALTER USER postgres PASSWORD 'mypw' Start the service and open psql shell: sudo service postgresql start & sudo -u postgres psql Give the 'postgres' user a password: sudo passwd postgres Install PostgreSQL: sudo apt install postgresql Update Ubuntu: sudo apt update & sudo apt upgrade Follow the instructions to enter your desired username and password. After login Ubuntu will automatically be installing, WSL2 and Ubuntu is standard on Windows 11. Open Windows Terminal/PowerShell as administrator (right click the start-icon on Windows 11 -> Windows Terminal (administrator). Run PostgreSQL on WSL (Windows Subsystem for Linux) and connect to it on Windows. You would want to know what is going on to troubleshoot the issue faster. To get an insight of the installation log, go to %TEMP% folder by searching for "%TEMP%" in the task bar, the log name would be bitrock_installer-xxx.log. just to check postgresql service starts automatically) Restarted computer -> HM2 runs properly (i.e. Installed HM2 -> created db successfully compmgmt.msc -> Local Users and Groups -> Users -> postgres -> Member of -> Add. compmgmt.msc -> Local Users and Groups -> Users -> postgres -> Member of -> Administrators -> Remove (this mean you must run the installation with the created postgres user) Checked data folder and confirmed files created successfully. runas /user:postgres cmd.exe -> cd \ -> postgresql-8.4.9-1-windows.exe -> installed successfully without errors. copy postgresql-8.4.9-1-windows.exe to C:\ > User name: postgres, Password: postgres -> Create Run > compmgmt.msc -> Local Users and Groups -> Users -> New User. Control Panel -> User Accounts -> Configure advanced user profile properties -> delete all "Unknown User" instances that seem to be left from postgres I would like to quickly recap the solution in case the the link expired The only approach that I luckily found after scratching my head nearly the whole day is with this post Install it on a place outside C:/ -> still failed.Choose the default installation folder that the setup prompted (C:/Program Files/PostgresSQL/11), and the data folder reside at other.Run installation as Administrator on every run -> failed.I have try these following approaches, but none of them work: Before that, I remove the current Postgres 9.6 (if I remember the version correctly), and attempt to install the new one Postgres 11, and got the issue. It's 2019, and I still have the same issue with Postgres 11.
