+		<para>Some packaged distributions of PostGIS (in particular the Win32 installers for PostGIS &gt;= 1.1.5) load the PostGIS functions into a template database called <varname>template_postgis</varname>. If the <varname>template_postgis</varname> database exists in your PostgreSQL installation then it is possible for users and/or applications to create spatially-enabled databases using a single command. Note that in both cases, the database user must have been granted the privilege to create new databases.</para>
