This maintenance release contains bugfixes since the 2.0.0 release. We deem it high priority for upgrading. In particular the fixes contained in this maintenance release address issues in continuous aggregates, compression, JOINs with hypertables and when upgrading from previous versions. **Bugfixes** * #2772 Always validate existing database and extension * #2780 Fix config enum entries for remote data fetcher * #2806 Add check for dropped chunk on update * #2828 Improve cagg watermark caching * #2842 Do not mark job as started when setting next_start field * #2845 Fix continuous aggregate privileges during upgrade * #2851 Fix nested loop joins that involve compressed chunks * #2860 Fix projection in ChunkAppend nodes * #2861 Remove compression stat update from update script * #2865 Apply volatile function quals at decompresschunk node * #2866 Avoid partitionwise planning of partialize_agg * #2868 Fix corruption in gapfill plan * #2874 Fix partitionwise agg crash due to uninitialized memory **Thanks** * @alex88 for reporting an issue with joined hypertables * @brian-from-quantrocket for reporting an issue with extension update and dropped chunks * @dhodyn for reporting an issue when joining compressed chunks * @markatosi for reporting a segfault with partitionwise aggregates enabled * @PhilippJust for reporting an issue with add_job and initial_start * @sgorsh for reporting an issue when using pgAdmin on windows * @WarriorOfWire for reporting the bug with gapfill queries not being able to find pathkey item to sort

-- For continuous aggregates: Copy ACL privileges (grants) from the
|
|
-- query view (user-facing object) to the internal objects (e.g.,
|
|
-- materialized hypertable, direct, and partial views). We want to
|
|
-- maintain the abstraction that a continuous aggregates is similar to
|
|
-- a materialized view (which is one object), so privileges on the
|
|
-- user-facing object should apply also to the internal objects that
|
|
-- implement the continuous aggregate. Having the right permissions on
|
|
-- internal objects is necessary for the watermark function used by
|
|
-- real-time aggregation since it queries the materialized hypertable
|
|
-- directly.
