To ensure that everything is set up properly, you should now run:
```
-bundle exec rake test:db
+bundle exec rails test:all
```
This test will take a few minutes, reporting tests run, assertions, and any errors. If you receive no errors, then your installation is successful.
# Installing compiled shared library database functions (optional)
-There are special database functions required by a (little-used) API call, the migrations and diff replication. The former two are provided as *either* pure SQL functions or a compiled shared library. The SQL versions are installed as part of the recommended install procedure above and the shared library versions are recommended only if you are running a production server making a lot of `/changes` API calls or need the diff replication functionality.

If you aren't sure which you need, stick with the SQL versions.
If you previously installed the SQL versions of these functions, we'll need to delete those before adding the new ones:
```
-psql -d openstreetmap -c "DROP FUNCTION IF EXISTS maptile_for_point"
psql -d openstreetmap -c "DROP FUNCTION IF EXISTS tile_for_point"
```
Then we create the functions within each database. We're using `pwd` to substitute in the current working directory, since PostgreSQL needs the full path.
```
-psql -d openstreetmap -c "CREATE FUNCTION maptile_for_point(int8, int8, int4) RETURNS int4 AS '`pwd`/db/functions/libpgosm', 'maptile_for_point' LANGUAGE C STRICT"
psql -d openstreetmap -c "CREATE FUNCTION tile_for_point(int4, int4) RETURNS int8 AS '`pwd`/db/functions/libpgosm', 'tile_for_point' LANGUAGE C STRICT"
psql -d openstreetmap -c "CREATE FUNCTION xid_to_int4(xid) RETURNS int4 AS '`pwd`/db/functions/libpgosm', 'xid_to_int4' LANGUAGE C STRICT"
```
