I don't see any ubuntu packages for 8.4 in the default repositories.
Does anybody know if they will be upgrading the postgresql package to 8.4 or creating a new package for it.
I'd rather use the packages than to compile it myself. If anybody has an argument as to why I should compile it I am all ears.
I just forwarded your message to Martin Pitt, he's the package maintain for Postgres for Ubuntu (and Debian, I believe). I don't know if this is planned for Karmic Koala (to be released in October).
