When linked the place may not be in the search index,
so it must be reindexed when being unlinked. The status
change will only have an effect during the subsequent
update, so change tests to that effect.
Avoids the occasional rounding problem which might occur when splitting
a line anywhere but on a support point, see postgis doc for ST_Split.
Fixes#253
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
