How to uninstall PostgreSQL

PostgreSQL is a powerful open source database system that leverages and extends the SQL language, combined with a host of features to securely store and scale the most complex data workloads. PostgreSQL has tons of various features designed to help developers build applications, administrators protect data integrity and create resilient environments, and help manage data regardless of dataset size.

PostgreSQL is not typically problematic, but if you are experiencing some issues with it, it is recommended to reinstall the application instead of trying to fix the problem. Thus, here we are going to explain how to uninstall PostgreSQL from a Mac computer easily and quickly.

This is a special uninstaller that will help you to completely uninstall any application from Mac along with their caches, logs, login items, preferences and browsers extensions.

How to remove PostgreSQL using Terminal

Deleting PostgreSQL just by dragging-and-dropping it into the Trash is not the correct way to uninstall apps. In this case, all the Postgre system service files will remain on your computer and keep cluttering up your disk space. Meaning, they will not let you correctly reinstall the app in the future.

To manage the complete Postgre uninstallation first of all, you should stop the Postgres server on your Mac. For this, click on the Elephant icon in the toolbar and select Shutdown server

If you installed Postgres with its Installer, then you can use the Terminal command line to remove Postgres. For this, go to the Applications folder, open Utilities subfolder, and launch Terminal. After that run the uninstaller using the following command:

If you get the message that this file does not exist, then skip to the second PostgreSQL removal way. If the command runs the uninstaller, proceed to the next steps.

Enter the administrator password to launch the uninstaller. Then follow the provided steps to remove the PostgreSQL and data folders.

Unfortunately, the root uninstaller doesn’t delete all service files of the program, so you will need to remove them manually. For this, use the commands below:

That’s all with the first method of removal. If for some reason this method does not work for you or you simply do not want to waste your time we recommend to uninstall PostgreSQL with the App Cleaner & Uninstaller tool, which will automatically find all support files of PostgreSQL and remove the application entirely. Keep reading this article to find out more about this tool.

The easiest way to remove PostgreSQL from Mac

Uninstalling PostgreSQL with Terminal may be a really time-consuming process. Moreover, you might have missed some service files and left them on your Mac’s hard drive. That’s why we recommend that you uninstall PostgreSQL automatically.

For the automatic uninstallation method, you need to use a special free cleanup application – App Cleaner & Uninstaller. This software automatically gathers all the service files of each app and allows you to uninstall them with one click. With this uninstaller, you can uninstall PostgreSQL without any extra steps and it will not take much of your time. Here are a few steps to do that:

Note that App Cleaner & Uninstaller automatically detects all the support files of the apps, so you don’t need to waste your time searching and removing them manually. That is why if you have already deleted PostgreSQL in a regular way, just by dragging-and-dropping it into the Trash, we recommend you to switch to the Remaining Files tab. That section will display all the leftovers of previously incorrectly deleted applications. So that is the perfect option to quickly get some free space.

Conclusion

In this article, we provided you with two ways of uninstalling PostgreSQL from Mac. You can uninstall it manually using the Terminal, which is a time-consuming task or you can follow the instruction of automatic uninstallation. Nektony recommends using a professional App Cleaner & Uninstaller tool. This application was developed specially for fast, safe, and complete uninstallation of any no longer needed application.

Как я могу полностью удалить Postgres со своего Mac?

Я не использовал MacPorts, Fink или другие инсталляторы Unix, кроме Homebrew, в жизни этого Mac. Homebrew отказывается от права собственности на установку Postgres:

Поэтому, несмотря на то, что я установлен, у меня сломана установка Postgres, которую я хотел бы полностью стереть

Как я могу полностью стереть Postgres из моей системы, чтобы я мог установить его с помощью установщика и получить одну установку Postgres вместо жутких полутора установок?

2 ответа 2

Похоже, вы только что удалили несколько файлов в Finder.

Предполагая, что вы использовали установщик отсюда, вы должны следовать инструкциям в руководстве по удалению:

Пробные

Если вам нужно удалить PostgreSQL, вы можете в любое время запустить деинсталлятор, созданный в процессе установки. Обратите внимание, что деинсталлятор никогда не удалит ваш каталог данных или учетную запись пользователя службы. Вы можете найти деинсталлятор в установочном каталоге и запустить его так же, как вы запустили инсталлятор. Обычно параметры командной строки не требуются. В Windows вы также можете запустить деинсталлятор из панели управления «Установка и удаление программ».

Другими словами, просто запустите деинсталлятор, установленный вместе с остальной частью программы.

После запуска любых деинсталляторов, следующее должно помочь вам найти любые оставшиеся файлы конфигурации или конфигурации SQL в вашем каталоге Library (общий источник странного поведения переустановки)

Если там есть что-то, что выглядит как часть установки PostgreSQL, удаление их перед переустановкой может помочь. Иногда там скрытые папки скрыты глубже.
