Completely uninstall PostgreSQL 9 0 4 from Mac OSX Lion

Question

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    gt  sudo find   -name   postgres                find   dev fd 3  Not a directory find   dev fd 4  Not a directory  Library Ruby Gems 1 8 doc activerecord-3 1 1 rdoc lib active record connection adapters postgresql
