I need help uninstalling PostgreSQL on my Mac running 10.7 I got PostgreSQL from here.

Since I'm on 10.7 OS X, I'm having problems.

I want to uninstall the software I got from enterprisedb.

Any tips?

There is a one-click uninstaller that removes everything except the data director and user account. The default data directory is /Library/PostgreSQL/$VERSION/data, so rm -rf that directory (or wherever you instructed the installer to create it).

To remove your postgres user (assuming it is named 'postgres'), first list your users to verify that the user 'postgres' and group 'postgres' are what you expect: (just a safe check) before deleting anything.


sudo dscl . -read /Users/postgres



sudo dscl . -read /Groups/postgres


Look for the "real name" field, to ensure that it matches the version of the db you are removing. 

Then remove the user and groups:


sudo dscl . -delete /Users/postgres



sudo dscl . -delete /Groups/postgres


Obviously, be careful when using sudo.
