When computing the address parts for a geometry, we need to do
a ST_Relates lookup in the location_area_large_* tables. This is
potentially very expensive for geometries with many vertices.
There is already a funtion for splitting large areas to reduce the
impact. This commit reduces the minimum area of a split, effectively
increasing the number of splits.
The effect on database size is minimal (around 3% increase), while
the indexing speed for streets increases by a good 60%.
Always add contents of addr:* tags into address part of the search
table, even when there is no corresponding other name. This keeps
search tolerant to the kind of tagging where parts show up in the
address that have no corresponding object in the database or where
it is only an unaddressable object.
A place needs all lower address rank object indexed to make up
the address. The search rank no longer ensures that as it can have
a different ordering than the address rank.
This switches indexing rank order to address ranks. Non-address
objects (with address rank 0) are indexed together with POIs.
Traffic signs rarely have name and are therefore mostly not
searchable. Remove them completely. Allow street lamps only when
they have a name. Removes about 2M object from a planet instance.
Before updating an admin boundary we need to make sure that any
artificially generated 'linked_place' entry is removed from the
extratags column. This ensures that the place designation does
not linger when a linked place disappears and that it is updated
when the linking changes.
An admin boundary might have a place tag but no matching place node.
We still should use the place value as indicator for the address
rank in this case.
Removes the defunct --osmosis-init and --no-api switches and the
unsupported (and unnecessary) deduplicate. Also removes
'experimental' from --setup-website as this is a required
function now.
After 6cc6cf950c names and house numbers
of POIS got mingled into a single item when creating the display name.
Add the house number as extra information without place_id to avoid
later mangling.
When the address rank of an admin boundary is changed because
of an attached place type, it may happen that the admin_level
hierarchy gets inversed. Avoid that by adjusting the address
rank if an inversion is detected.
Make access to the DB object a function, so that the connection
can be opened implicitly when the object is accessed for the first
time. This way we no longer need to check beforehand if a specific
function of the setup needs DB access or not.
Also move the check for the module to the relevant sub step.
