-    The default installation no longer compiles the PostgreSQL module that

-    are upgrading an older database or want to run the

-    cmake: `cmake -DBUILD_MODULE=on ../Nominatim`. To compile the module

 Nominatim installs itself into `/usr/local` per default. To choose a different
 installation directory add `-DCMAKE_INSTALL_PREFIX=<install root>` to the
 cmake command. Make sure that the `bin` directory is available in your path
