I don't use the same version, but uninstall actions are the same: Looking for file uninstall-postgresql inside directory

to delete all unnecessary directory.

Answer 2

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.

Answer 3

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.
