When using a linked place as centroid for a boundary, check
first that it is really within the area. If it is outside,
just keep the computed centroid because a centroid outside the
area just causes havok.
Fixes#1352.
If a boundary relation has no label member preferably
link against a place node with the same place type.
Also inherit the rank_address from the place node (only
has an effect when linking via lable member or place type).
The function only ever returns one result of which only the
place_id is used. So simplify it to return a single place_id
only (or NULL if none is found).
Also fix typo in function name.
The function only ever returns one result of which only the
place_id is used. So simplify it to return a single place_id
only (or NULL if none is found). Rename funciton to avoid
conflicts when updating an existing database.
Instead of unconditionally parenting them to a street, the
larger areas get a parent area that contains them. To keep
things computationally light-weight, only use the centroid and
bbox to determine if an area is contained.
Requires renaming of parenting functions because renaming
a parameter of the function causes issues when updating the
function (it requires a manual delete, which I'd like to
avoid).
Normally ST_Covers() should include a bbox index use,
so adding a bbox where clause is not really necessary.
However, the query planner messes up and uses a parallel
index search with a second index instead of exclusively
running on the geometry index, when the bbox part is
missing.
When --drop is given, we can remove all node geometry information
already after the import with osm2pgsql. Also drop all unnecessary
tables before creating the final indices.
Remove index on name_vector. We always do near search where the
geometry index is sufficient. Also split centroid index in low
and high rank indexes. Reduces index size by about 25%.
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.
