pgPointcloud extension
|
|
------------------------------------------------------------------------------
|
|
|
|
Once a new version of pgPointcloud installed, you may want to update your
|
|
databases where the extension is already in use. The first thing to compare is
|
|
the version currently used with versions actually available on your system:
|
|
|
|
.. code-block:: sql
|
|
|
|
SELECT pc_version();
|
|
--> 1.1.1
|
|
|
|
SELECT version FROM pg_available_extension_versions WHERE name ='pointcloud';
|
|
--> 1.1.1
|
|
--> 1.2.1
|
|
|
|
|
|
Then you can update to the latest version with ``ALTER EXTENSION pointcloud
|
|
UPDATE`` or target a specific version:
|
|
|
|
.. code-block:: sql
|
|
|
|
ALTER EXTENSION pointcloud UPDATE TO '1.2.1';
|
|
|
|
SELECT pc_version();
|
|
--> 1.2.1
|
|
|
|
|
|
.. warning::
|
|
|
|
The GHT compression has been removed in the 1.2.0 version. Unfortunately,
|
|
you have to remove the compression on your tables before updating the
|
|
extension from 1.1.x to a higher version. Some information are available in
|
|
the `Schema and compression`_ tutorial.
