installation postgres

[Rafnews]

Hi,

using the GUI version of add/remove software from F10 under Gnome i tried to
install postgresql 8.3.5.
i can see the client and server package are checked in this GUI version, but
i do not find any folder where it is installed.
basically the postgresql.conf file is located somewhere after
installation...but in my case is nowhere :-(
what's wrong ? is anything OK in F10 regarding PostgreSQL installation ?

if i download the bin file from www.postgresql.org page, installation works
perfectly, so what's wrong with GUI add/remove software ?
thx.
