There was a problem hiding this comment.
Won't this orphan a compressed chunk if the uncompressed chunk is marked as dropped? In short, what if compressed_chunk_id refers to a chunk that actually exists?
There was a problem hiding this comment.
no we only keep metadata of uncompressed chunk
The check for existence of compressed chunks when disabling compression would not ignore dropped chunks making it impossible to disable compression on hypertables with continuous aggregates that had dropped chunks. This patch ignores dropped chunks in this check and also sets compressed_chunk_id to NULL in the metadata for deleted chunks.

This maintenance release contains bugfixes since the 1.7.4 release. The most of the fixes were ported from 2.0.0 and 2.0.1 releases. We deem it high priority for upgrading for users on 1.7.4 or previous versions. 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** * timescale#2502 Replace check function when updating * timescale#2558 Repair dimension slice table on update * timescale#2619 Fix segfault in decompress_chunk for chunks with dropped columns * timescale#2664 Fix support for complex aggregate expression * timescale#2800 Lock dimension slices when creating new chunk * timescale#2860 Fix projection in ChunkAppend nodes * timescale#2865 Apply volatile function quals at decompresschunk * timescale#2851 Fix nested loop joins that involve compressed chunks * timescale#2868 Fix corruption in gapfill plan * timescale#2883 Fix join qual propagation for nested joins * timescale#2885 Fix compressed chunk check when disabling compression * timescale#2920 Fix repair in update scripts **Thanks** * @akamensky for reporting several issues including segfaults after version update * @alex88 for reporting an issue with joined hypertables * @dhodyn for reporting an issue when joining compressed chunks * @diego-hermida for reporting an issue with disabling compression * @Netskeh for reporting bug on time_bucket problem in continuous aggregates * @WarriorOfWire for reporting the bug with gapfill queries not being able to find pathkey item to sort * @zeeshanshabbir93 for reporting an issue with joins

It also includes enhancements to continuous aggregates, including improved validation of policies and optimizations for faster refreshes when there are a lot of invalidations. **Minor features** * #2926 Optimize cagg refresh for small invalidations **Bugfixes** * #2850 Set status for backend in background jobs * #2883 Fix join qual propagation for nested joins * #2884 Add GUC to control join qual propagation * #2885 Fix compressed chunk check when disabling compression * #2908 Fix changing column type of clustered hypertables * #2942 Validate continuous aggregate policy **Thanks** * @zeeshanshabbir93 for reporting the issue with full outer joins * @Antiarchitect for reporting the issue with slow refreshes of * @diego-hermida for reporting the issue about being unable to disable compression * @mtin for reporting the issue about wrong job status

This maintenance release contains bugfixes since the 1.7.4 release. Most of these fixes were backported from the 2.0.0 and 2.0.1 releases. We deem it high priority for upgrading for users on TimescaleDB 1.7.4 or previous versions. 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** * timescale#2502 Replace check function when updating * timescale#2558 Repair dimension slice table on update * timescale#2619 Fix segfault in decompress_chunk for chunks with dropped columns * timescale#2664 Fix support for complex aggregate expression * timescale#2800 Lock dimension slices when creating new chunk * timescale#2860 Fix projection in ChunkAppend nodes * timescale#2865 Apply volatile function quals at decompresschunk * timescale#2851 Fix nested loop joins that involve compressed chunks * timescale#2868 Fix corruption in gapfill plan * timescale#2883 Fix join qual propagation for nested joins * timescale#2885 Fix compressed chunk check when disabling compression * timescale#2920 Fix repair in update scripts **Thanks** * @akamensky for reporting several issues including segfaults after version update * @alex88 for reporting an issue with joined hypertables * @dhodyn for reporting an issue when joining compressed chunks * @diego-hermida for reporting an issue with disabling compression * @Netskeh for reporting bug on time_bucket problem in continuous aggregates * @WarriorOfWire for reporting the bug with gapfill queries not being able to find pathkey item to sort * @zeeshanshabbir93 for reporting an issue with joins

The check for existence of compressed chunks when disabling
compression would not ignore dropped chunks making it impossible
to disable compression on hypertables with continuous aggregates
that had dropped chunks.
This patch ignores dropped chunks in this check and also sets
compressed_chunk_id to NULL in the metadata for deleted chunks.
Fixes #2844
