How do I Remove Postgre 8.1.11 with dependancies?

delete all depending packages first:

in this case, delete the package postgresql-python-8.1.11.el5_1.1.i38 before deleting postgres.

I am not 100% sure if there is an more efficient way in cent-os, but at least you can delete all your packages, just make sure to delete the dependencies first.

Will deleting PostgreSQL 8.1.22 package and dependacies cause issues for an updated version of PostgreSQL and its dependancies? This is my goal to have a clean RHEL OS and have the latest version of PostgreSQL 9.0 installed.

Thanks, Missymadi

No, you won't have any issues. These are packages that depend on postgresql 8.1, which have nothing to do with the 9.1 version.

I just tried to remove the dependancy
rm libpq.so.4

error - no such file or directory.
How do I delete dependancies?

a dependency is also a rpm package.

you have to remove the installed packages. If you have yum installed you can use it to remove all packages including the dependency packages:
yum remove <package name>

I do not know how the package name of postgresql is exactly in redhat, but you can find out by:

rpm -qa | grep -i postgres

this should list all installed packages regarding postgres, you can remove them also with:

rpm -e <packagename1> <packagename2> ... from the list of packages you received from rpm -qa.

bash grep -i not found error.

Strange - I entered
rpm -e libpq.so.4   and recieved the following error:
error: Package libpq.so.4 is not installed.
