+# Mapobject-Database
+
+The mapobject database is for all the mapobjects (POI, Shops, etc)
+Per default it is initialized as a sqlite3 database in `mapserver.sqlite3`
+
+If you want to store your mapobjects in a proper database or need performance at
+scale you can configure a postgresql server in your `world.mt`:
+
+```
+pgsql_mapserver_connection = host=127.0.0.1 port=5432 user=postgres password=enter dbname=postgres
+```
+
+The syntax is the same as for `pgsql_connection`
