SQL statements should be executed from the PostgreSQL commandline. Execute
`psql nominatim` to enter command line mode.
+## 3.6.0 -> master
+
+### Status table contains now time zone information
+
+The `import_status` table has been changed to include timezone information
+with the time stamp. You need to alter an existing table before running
+any replication functions with:
+
+```sql
+ALTER TABLE import_status ALTER COLUMN lastimportdate TYPE timestamp with time zone;
+```
+
+### New location for data files
+
+External data files for Wikipedia importance, postcodes etc. are no longer
+expected to reside in the source tree by default. Instead they will be searched
+in the project directory. If you have an automated setup script you must
+either adapt the download location or explicitly set the location of the
+files to the old place in your `.env`.
+
+### Introducing `nominatim` command line tool
+
+The various php utilities have been replaced with a single `nominatim`
+command line tool. Make sure to adapt any scripts. There is no direct 1:1
+matching between the old utilities and the commands of nominatim CLI. The
+following list gives you a list of nominatim sub-commands that contain
+functionality of each script:
+
+* ./utils/setup.php: `import`, `freeze`, `refresh`
+* ./utils/update.php: `replication`, `add-data`, `index`, `refresh`
+* ./utils/specialphrases.php: `special-phrases`
+* ./utils/check_import_finished.php: `admin`
+* ./utils/warm.php: `admin`
+* ./utils/export.php: `export`
+
+Try `nominatim <command> --help` for more information about each subcommand.
+
+`./utils/query.php` no longer exists in its old form. `nominatim search`
+provides a replacement but returns different output.
+
+## 3.5.0 -> 3.6.0
+
+### Change of layout of search_name_* tables
+
+The table need a different index for nearest place lookup. Recreate the
+indexes using the following shell script:
+
+```bash
+for table in `psql -d nominatim -c "SELECT tablename FROM pg_tables WHERE tablename LIKE 'search_name_%'" -tA | grep -v search_name_blank`;
+do
+ psql -d nominatim -c "DROP INDEX idx_${table}_centroid_place; CREATE INDEX idx_${table}_centroid_place ON ${table} USING gist (centroid) WHERE ((address_rank >= 2) AND (address_rank <= 25)); DROP INDEX idx_${table}_centroid_street; CREATE INDEX idx_${table}_centroid_street ON ${table} USING gist (centroid) WHERE ((address_rank >= 26) AND (address_rank <= 27))";
+done
+```
+
+### Removal of html output
+
+The debugging UI is no longer directly provided with Nominatim. Instead we
+now provide a simple Javascript application. Please refer to
+[Setting up the Nominatim UI](../Setup-Nominatim-UI) for details on how to
+set up the UI.
+
+The icons served together with the API responses have been moved to the
+nominatim-ui project as well. If you want to keep the `icon` field in the
+response, you need to set `CONST_MapIcon_URL` to the URL of the `/mapicon`
+directory of nominatim-ui.
+
+### Change order during indexing
+
+When reindexing places during updates, there is now a different order used
+which needs a different database index. Create it with the following SQL command:
+
+```sql
+CREATE INDEX idx_placex_pendingsector_rank_address
+ ON placex
+ USING BTREE (rank_address, geometry_sector)
+ WHERE indexed_status > 0;
+```
+
+You can then drop the old index with:
+
+```sql
+DROP INDEX idx_placex_pendingsector;
+```
+
+### Unused index
+
+This index has been unused ever since the query using it was changed two years ago. Saves about 12GB on a planet installation.
+
+```sql
+DROP INDEX idx_placex_geometry_reverse_lookupPoint;
+```
+
+### Switching to dotenv
+
+As part of the work changing the configuration format, the configuration for
+the website is now using a separate configuration file. To create the
+configuration file, run the following command after updating:
+
+```sh
+./utils/setup.php --setup-website
+```
+
+## 3.4.0 -> 3.5.0
+
+### New Wikipedia/Wikidata importance tables
+
+The `wikipedia_*` tables have a new format that also includes references to
+Wikidata. You need to update the computation functions and the tables as
+follows:
+
+ * download the new Wikipedia tables as described in the import section
+ * reimport the tables: `./utils/setup.php --import-wikipedia-articles`
+ * update the functions: `./utils/setup.php --create-functions --enable-diff-updates`
+ * create a new lookup index:
+```sql
+CREATE INDEX idx_placex_wikidata
+ ON placex
+ USING BTREE ((extratags -> 'wikidata'))
+ WHERE extratags ? 'wikidata'
+ AND class = 'place'
+ AND osm_type = 'N'
+ AND rank_search < 26;
+```
+ * compute importance: `./utils/update.php --recompute-importance`
+
+The last step takes about 10 hours on the full planet.
+
+Remove one function (it will be recreated in the next step):
+
+```sql
+DROP FUNCTION create_country(hstore,character varying);
+```
+
+Finally, update all SQL functions:
+
+```sh
+./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
+```
+
## 3.3.0 -> 3.4.0
### Reorganisation of location_area_country table
CREATE INDEX idx_location_area_country_place_id ON location_area_country USING BTREE (place_id);
```
+Finally, update all SQL functions:
+
+```sh
+./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
+```
+
## 3.2.0 -> 3.3.0
### New database connection string (DSN) format
### Natural Earth country boundaries no longer needed as fallback
-```
+```sql
DROP TABLE country_naturalearthdata;
```
The reverse algorithm has changed and requires new indexes. Run the following
SQL statements to create the indexes:
-```
+```sql
CREATE INDEX idx_placex_geometry_reverse_lookupPoint
- ON placex USING gist (geometry)
- WHERE (name is not null or housenumber is not null or rank_address between 26 and 27)
- AND class not in ('railway','tunnel','bridge','man_made')
- AND rank_address >= 26 AND indexed_status = 0 AND linked_place_id is null;
+ ON placex
+ USING gist (geometry)
+ WHERE (name IS NOT null or housenumber IS NOT null or rank_address BETWEEN 26 AND 27)
+ AND class NOT IN ('railway','tunnel','bridge','man_made')
+ AND rank_address >= 26
+ AND indexed_status = 0
+ AND linked_place_id IS null;
CREATE INDEX idx_placex_geometry_reverse_lookupPolygon
ON placex USING gist (geometry)
WHERE St_GeometryType(geometry) in ('ST_Polygon', 'ST_MultiPolygon')
- AND rank_address between 4 and 25 AND type != 'postcode'
- AND name is not null AND indexed_status = 0 AND linked_place_id is null;
+ AND rank_address between 4 and 25
+ AND type != 'postcode'
+ AND name is not null
+ AND indexed_status = 0
+ AND linked_place_id is null;
CREATE INDEX idx_placex_geometry_reverse_placeNode
ON placex USING gist (geometry)
- WHERE osm_type = 'N' AND rank_search between 5 and 25
- AND class = 'place' AND type != 'postcode'
- AND name is not null AND indexed_status = 0 AND linked_place_id is null;
+ WHERE osm_type = 'N'
+ AND rank_search between 5 and 25
+ AND class = 'place'
+ AND type != 'postcode'
+ AND name is not null
+ AND indexed_status = 0
+ AND linked_place_id is null;
```
You also need to grant the website user access to the `country_osm_grid` table:
-```
+```sql
GRANT SELECT ON table country_osm_grid to "www-user";
```
You can now drop the unused indexes:
-```
+```sql
DROP INDEX idx_placex_reverse_geometry;
```
CREATE UNIQUE INDEX idx_postcode_id ON location_postcode USING BTREE (place_id);
CREATE INDEX idx_postcode_postcode ON location_postcode USING BTREE (postcode);
GRANT SELECT ON location_postcode TO "www-data";
