If  you used "apt install" to install it in the first place, then yes,
"apt remove" is the only way to remove it cleanly.

Note that this won't delete the data directory - you'll need to use the
Debian-specific script pg_dropcluster to do this. Also, I don't think it
removes the config files in /etc/postgresql, though "apt purge" should
do for those.

Not really. Per here:

https://www.postgresql.org/download/linux/ubuntu/

Ubuntu 24 is supported, You would just have to change the repo to:

... noble-pgdg ...

is apt remove an effective way to uninstall or is there a better method?

Otherwise follow Raymond O'Donnell's suggestions to uninstall/purge.

Or rethink that docker choice...
