The country information can be determined sufficiently from
the country code. We only loose the specific OSM object
behind the address.
Also streamlines the location_area_country table.
When roads cross boundaries, both administrative entities should
be added to the address list, so that both entities can be used
for searching. Also allows in a second step to better sort out
addresses of POIs on such roads.
Fixes#121.
Name of function was changed in postgis 2.1 and now prints ugly
deprecation warnings. For older versions of postgis, function
will be renamed to the new name during the setup of the DB.
To update existing databases with postgis < 2.1 run:
ALTER FUNCTION st_line_interpolate_point(geometry, double precision) RENAME TO ST_LineInterpolatePoint
and then reinstall the SQL functions:
./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
Removes 'trigram' and 'location' from word.
Removes 'address', 'importance' and 'country_code' from search_name_*.
Use full geometry in centroid column of search_name_*.
Requires migration of existing tables. For more info see pull request
