How to uninstall PostgreSQL manually.

You may sometime wish to ‘clean’ the machine down and remove all traces of PostgreSQL. There are a series of steps for this:

–> Well, when uninstalling the server package, all running process are stopped ,you don’t have to stop it.

–> Lists your installed PostgreSQL packages  [  rpm -qa|grep postg ]

–> Remove the RPMs [ rpm -e package-name ]  if you remove all RPMs in one command, the order is irrelevant. If you remove them one at a time, you need to remove them in the order docs, jdbc, server, mainrpm and libs with docs first in order to avoid dependency problems.

–> And incase if you have multiple entries of PostgreSQL packages with same name use [  rpm -e --nodeps --allmatches package-name ]
