Log message:
geography/osm2pgsql: Update to 1.9.2
The old version was quite behind and stopped building. This version
packages and the main program runs; therefore it is better, even if
not tested.
Packaging changes:
Take MAINTAINERship (ok wiedi@).
Adjust dependencies to match upstream docs.
Hack in finding boost headers (should not be necessary).
Upstream NEWS content: (Much has changed and this summary omits much,
including bug-fix releases entirely. See
https://github.com/osm2pgsql-dev/osm2pgsql/releases for more details
-- there is no NEWS.)
Release 1.9.0
This release brings three new major features:
a new osm2pgsql_properties table that saves command line options and reuses \
them on updates
a new database middle saves raw OSM data in JSONB format and is explicitly \
designed to be queried by the user
the new (and still experimental) osm2pgsql-gen adds geometry generalization \
to osm2pgsql (thanks @joto)
Release 1.8.0
The largest change is the addition of much more flexible index support in the \
flex output. The table definitions have a new (optional) field called indexes \
now which takes a list of index definitions. If the field is not there, we fall \
back to what we did before and create a GIST index on the only/first geometry \
column of a table. But you can also define any kind of index you want: define \
which index method (BTREE, GIST, ...) to use on which columns, define WHERE \
clauses and expression indexes and much more. See the flex-config/indexes.lua \
Lua config for some usage examples and the manual for all the details. You can \
also force osm2pgsql to always build the id indexes which are normally only \
built in slim mode.
The gazetteer output and the command line option --with-forward-dependencies are \
deprecated in this release and will be removed soon. They were only needed for \
Nominatim which switched to using the flex output recently.
Here are the other changes:
Fix a problem when using osm2pgsql with a projection other than WGS84 \
(EPSG:4326) or Web Mercator (EPSG:3857) which made the program really slow.
New pole_of_inaccessibility() Lua function to generate reasonably good label \
points from polygons. (This function is currently marked as experimental, which \
means it can change without notice at any time.)
Release 1.7.0
For this version we rebuilt a lot of the code around geometry processing and \
around expire. The different parts -- creation of geometries from OSM data, \
transforming geometries (like merging and splitting linestrings) and finally \
writing them out in WKB format for import into the database -- are now well \
separated and tested on their own. And we added some functions for geometry \
processing, too. osm2pgsql can now calculate the centroid of a polygon and \
simplify linestrings using the Douglas-Peucker algorithm.
But the best part is that all of that new geometry goodness is now available \
from the Lua config files when using the flex output. There are many new ways of \
processing geometries from Lua:
The get_bbox() is now available for relations, too.
There are new functions as_point(), as_linestring(), as_polygon(), \
as_multilinestring(), as_multipolygon(), and as_geometrycollection() to create \
geometries from OSM objects.
Geometries can be manipulated in Lua with several functions modeled after \
the same functions in PostGIS: area(), centroid(), geometry_type(), \
line_merge(), num_geometries(), segmentize(), simplify(), srid(), and \
transform(). We expect more to come in the future. This way you can do more \
geometry processing on import removing the need for some post-processing in SQL.
We used to have the somewhat magic handling of geometries with the add_row() \
function which only allowed a limited set of operations. This function is still \
available for backwards compatibility, but there is a new function insert() now \
which doesn't have this magic. Instead geometries are treated like any other \
data type giving you a lot more flexiblity. Check out the example config files \
addresses.lua, generic.lua, simple.lua and geometries-using-insert.lua in the \
flex-config directory for some ideas on what can be done.
In this version we enabled the bucket index for way nodes by default. This had \
been around for a while but you needed a command line option to enable it. After \
some positive feedback from the community we decided to make this the new \
default. It will be used on new imports (existing databases will keep using the \
old index). The new bucket index is much smaller and can save you hundreds of \
gigabytes of disk space. See
https://osm2pgsql.org/doc/manual.html#bucket-index-for-slim-mode for the details.
Release 1.6.0
The osm2pgsql-replication script which has been included in the osm2pgsql \
repository for a while will now be installed together with its man page on \
"make install". To use it you need Python3, psycopg2 (or psycopg3), \
and PyOsmium installed. See the manual for details.
Release 1.5.0
This release brings quite a lot of improvements. We removed the \
"experimental" label from the flex output which we introduced in \
version 1.3.0. There are some small changes you might have to make to your flex \
configurations, see the Upgrading chapter of the manual for details.
This release also contains a rewrite of the code used to temporarily store OSM \
data in memory while processing the data in non-slim mode, i.e. when you import \
data without --slim. It now uses much less memory.
Release 1.4.0
The project has a new website at https://osm2pgsql.org now with extensive \
documentation and examples, and with sections on support, contributing, news, \
etc. Most of the documentation from the repository and the OSM wiki was moved \
there. We still have a man page, it is now maintained in markdown format. All \
the documentation, man page, help texts etc. have been cleaned up, made more \
consistent and brought up to date.
The program has a much improved log output now. Each line is prefixed with a \
date/timestamp and by default osm2pgsql isn't as verbose any more. You can \
change the verbosity using several options. You can even have super-verbose \
logging of all SQL commands issued and all data written to the database. \
Warnings and errors now appear in red color if your console supports it. \
Progress output can be disabled, for instance, when the output is redirected to \
a file. When printing how low something took, osm2pgsql will now not only print \
the seconds but also a more human readable format with hours, minutes, and \
seconds.
In the last release (version 1.3.0) we have already added a warning when you \
used input files with negative OSM object ids or input files which are not \
ordered correctly. These are now not allowed any more and osm2pgsql will stop \
with an error if it detects these. See the manual for how to work around this. \
This allowed us to improve the handling of multiple input files. Osm2pgsql now \
reads multiple input files at the same time merging the contents. This means \
that you can now import several extracts in one go. Note that the extracts still \
have to come from the same point in time!
Changes in the flex output (which is still marked experimental). Not that some \
of these are breaking changes compared to the behaviour in version 1.3.0:
Fix: Flex output sometimes created two id indexes on the same table.
Set projection for geometry columns in the table configuration. The command \
line options --latlong, -m, --merc, -E, and --proj are not used by the flex \
output any more.
Flex mode setting type_column fixed. Now also supports id columns compatible \
with Imposm.
Optionally wrap polygon geometries in multipolygons if the geometry column \
of the target table is of type MultiPolygon.
Switch multipolygon generation from default off to default on. The multi \
option on the area geometry transformation has been removed and there is a new \
option split_at.
Add several Lua helper functions for flex config files.
