PostgreSQL on my Mac - did I install it? how do I uninstall it? [closed]

Question

Sorry for this noob question, but I'm not sure what I just did regarding PostgreSQL. I downloaded and installed Postres.app from http://postgresapp.com/ Then I decided that I no longer wanted it and would rather just install PostgreSQL with Homebrew. So I dragged Postgres.app from my applications folder to my trash and then cleaned my trash and rebooted. Now I'm discovering that I can run psql from the command line with no problem and I appear to be able to create and connect to PostgreSQL databases and so forth. So my question is: was PostgreSQL already installed on my system (Mac 10.8.2 - Mountain Lion)? When I installed Postgres.app, was that just a wrapper that started and stopped the database for me? (If so, why was it a 28 MB download?) Or did I install PostgreSQL when I installed Postgres.app?

According to this you've done ok with the Trash. You can go through the list of folders it mentions as installation directories and remove them if still present:

• Binaries: /Applications/Postgres.app/Contents/MacOS/bin
• Headers: /Applications/Postgres.app/Contents/MacOS/include
• Libraries: /Applications/Postgres.app/Contents/MacOS/lib
• Shared Libraries: /Applications/Postgres.app/Contents/MacOS/share
• Data: ~/Library/Application\ Support/Postgres/var

Also you can check your psql installation running:

$ which psql

It should come from /usr/bin/ if it was installed properly by some source (macports, brew) and I presume the PostgresApp used its own bin folder for it.
