## 1 Installation hints

Maybe your distribution provides the database package.

If not, or if you want a newer version, Octaves `pkg` command allows building the package from source and installing it. Note that you have to `load` any Octave package before you can use it. See Octaves documentation of `pkg`.

In building from source with `pkg`, some preconditions of the system are checked, in particular the presence of the `pq` library of Postgresql. If you have to install a package of your operating system with `libpq`, you usually also need to install the so called development package (named `libpq-dev` or similar).
