This allows address interpolations to work correctly when flatnode storage
is used for node coordinates.
To fix interpolations in an existing database, follow these steps:
* invalidate all interpolations (in psql):
`UPDATE placex SET indexed_status=2 WHERE rank_search = 28`
* disable updates:
./utils/setup.php --create-functions --create-partition-functions
* reindex the whole lot:
./utils/update.php --index --index-instances <number of your cpus>
* enable updates again:
./utils/setup.php --create-functions --enable-diff-updates --create-partition-functions
Avoids to a certain extent propagation of misassignment of
partitions when a country is expanded so far into another
that the centroid ends up in this other country.
Also added a sanity check to ensure that accidental removal of admin_level
tags on large areas doesn't cause huge reindexing load. That can be disabled
by setting CONST_Limit_Reindexing to false.
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
This might happen for nameless landuse/natural objects that are added to place
during initial import but then dropped when being copied to placex.
If they later receive a name, thus becoming valid, then place_insert should
delete the orphan object in place and reinsert it. If they are large enough,
the place_delete trigger prevents them from being removed. The additional
update fools the delete trigger.
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
