问题
This question may look like a duplicate of: How to uninstall postgresql on my Mac (running Snow Leopard) however, there are two major differences. I'm running Lion and I'm trying to uninstall PostgreSQL 9.0.4. I've looked at the last question and the link that it referenced, but I did not find a file called "uninstall-postgresql" when I run this command:
sudo find / -name "*uninstall-*"
So, I assume this means that the uninstall process for 9.0.4 is different than that of 8.x.
I've seen a couple of posts in different places describing a method for manual uninstallation but, similarly, some of the directories/files referenced are not present on my machine.
Any assistance or direction you can provide would be greatly appreciated.
Just for reference, this is the link the other poster used to uninstall postgres from snow leopard. As I tried to step through these commands, most of them choked with some variant of "command not found".
UPDATE:
In addition to brew uninstall postgres, should I remove any of the following files/directories manually? Keep in mind I want to completely wipe the slate clean, no data files/database tables or anything.

homebrew Installer
Assuming you installed PostgreSQL with homebrew as referenced in check status of postgresql server Mac OS X and how to start postgresql server on mac os x: you can use the brew uninstall postgresql command.
EnterpriseDB Installer
If you used the EnterpriseDB installer then see the other answer in this thread.
The EnterpriseDB installer is what you get if you follow "download" links from the main Postgres web site. The Postgres team releases only source code, so the EnterpriseDB.com company builds installers as a courtesy to the community.
Postgres.app
You may have also used Postgres.app.
This double-clickable Mac app contains the Postgres engine.
回答2:
The following is the un-installation for PostgreSQL 9.1 installed using the EnterpriseDB installer. You most probably have to replace folder /9.1/ with your version number. If /Library/Postgresql/ doesn't exist then you probably installed PostgreSQL with a different method like homebrew or Postgres.app.
To remove the EnterpriseDB One-Click install of PostgreSQL 9.1:
- Open a terminal window. Terminal is found in: Applications->Utilities->Terminal
Run the uninstaller:
sudo /Library/PostgreSQL/9.1/uninstall-postgresql.app/Contents/MacOS/installbuilder.shIf you installed with the Postgres Installer, you can do:
open /Library/PostgreSQL/9.2/uninstall-postgresql.appIt will ask for the administrator password and run the uninstaller.
Remove the PostgreSQL and data folders. The Wizard will notify you that these were not removed.
sudo rm -rf /Library/PostgreSQLRemove the ini file:
sudo rm /etc/postgres-reg.iniRemove the PostgreSQL user using System Preferences -> Users & Groups.
- Unlock the settings panel by clicking on the padlock and entering your password.
- Select the PostgreSQL user and click on the minus button.
Restore your shared memory settings:
sudo rm /etc/sysctl.conf
That should be all! The uninstall wizard would have removed all icons and start-up applications files so you don't have to worry about those.
回答3:
I don't use the same version, but uninstall actions are the same: Looking for file uninstall-postgresql inside directory
/Library/PostgreSQL/9.6
then run it.
(Screenshot in macOS 10.13)
then
sudo rm -rf /Library/PostgreSQL/
to delete all unnecessary directory.
回答4:
I was not able to uninstall PostgreSQL 9.0.8. But I finally found this. (I installed Postgres using homebrew)
brew list
Look for the correct folder name. Something like.
postgresql9
Once you find the correct name do:
brew uninstall postgresql9
That should uninstall it.
回答5:
This blog post explains very well:
(just replace 9.X by your version. e.g: 9.6)
A. If installed PostgreSQL with homebrew, enter brew uninstall postgresql
B. If you used the EnterpriseDB installer, follow the following step.
Run the uninstaller on terminal window: sudo /Library/PostgreSQL/9.X/uninstall-postgresql.app/Contents/MacOS/installbuilder.sh
C. If installed with Postgres Installer, do:
open /Library/PostgreSQL/9.X/uninstall-postgresql.app
Remove the PostgreSQL and data folders. The Wizard will notify you that these were not removed.
sudo rm -rf /Library/PostgreSQL
Remove the ini file:
sudo rm /etc/postgres-reg.ini
Remove the PostgreSQL user using System Preferences -> Users & Groups.
Unlock the settings panel by clicking on the padlock and entering your password.
Select the PostgreSQL user and click on the minus button.
Restore your shared memory settings: sudo rm /etc/sysctl.conf
回答6:
Uninstallation :
sudo /Library/PostgreSQL/9.6/uninstall-postgresql.app/Contents/MacOS/installbuilder.sh
Removing the data file :
sudo rm -rf /Library/PostgreSQL
Removing the configs :
sudo rm /etc/postgres-reg.ini
And thats it.
回答7:
open terminal and type the below command and hit enter
sudo /Library/PostgreSQL/9.X/uninstall-postgresql.app/Contents/MacOS/installbuilder.sh
回答8:
If you installed using the graphical installer by BigSQL from the official postgres site and if you installed in the default location...
You can find your uninstaller in your home directory: /Users/<yourusername/PostGreSQL/uninstall/
回答9:
Incase you have multiple versions of Postgres installed on your machine. You can remove all via brew command as:
brew uninstall --force postgresql
