Applications tab in KDE

["Alain Roger" <raf news gmail com>]

Hi,

I was successful to install KDE on F10 and to use this wonderfull environment.
However, i tried to install PostgreSQL from official Add/Remove Software application (server + client) but after clicking on Apply, F10 downloaded some packages and nothing more was done.
i was looking for if F10 installed those packages as normally a /var/lib/pgsql/postgresql.conf file has to be created but nothing as such and nothing also somewhere else (i tried find / -name 'postgresql.conf' as root.

1. how is it possible ? the packages are not installed automatically ?
2. how can i checked if such package is correctly installed ?

after that, i decided to download it by myself in tmp folder and i installed it.
first of all, this bin file installs by default under /opt/postgresql/8.3/ ...

but my main issue is the following. after installation F10 has created a tab/folder (PostgreSQL 8.3), under Application menu.

3. how can i create my own tab/folder for hosting programs ?
4. how can i move the postgreSQL 8.3 program files/folder/tab from application menu to my new tab/folder from point 3 ?

thanks a lot,
