In my Debian 12, I have removed the following apps from my system by using the following commands:
sudo apt-get –purge remove postgresql postgresql-15 postgresql-client-common postgresql-common postgresql-contrib
sudo apt-get –purge remove postgresql postgresql-12 postgresql-client-common postgresql-common postgresql-contrib
and then used sudo apt autoremove to remove whatever was left dangling there. However, after using dpkg -l | grep postgres command, I get this?
dpkg -l | grep postgres
rc postgresql-12 12.15-1.pgdg120+1 amd64 The World's Most Advanced Open Source Relational Database
rc postgresql-15 15.3-1.pgdg120+1 amd64 The World's Most Advanced Open Source Relational Database
rc postgresql-client-common 250.pgdg120+1 all manager for multiple PostgreSQL client versions
rc postgresql-common 250.pgdg120+1 all PostgreSQL database-cluster manager
rc postgresql-pljava-common 1.6.4-2.pgdg120+1 all Java procedural language for PostgreSQL, config files
-----------------------------
The above clearly shows that dpkg, and therefore my Debian 12, still recognize the existence of these packages. When trying to remove them apt remove, it fails to find them.
How can I completely remove PostgreSQL-xx.xx from my system?
Thanks!
