Fix segfault creating cagg with NULL bucket width #6297

Conversation

Contributor

When creating a Continuous Aggregate using a NULL bucket_width in the time_bucket function it lead to a segfault, for example:

CREATE MATERIALIZED VIEW cagg WITH (timescaledb.continuous) AS SELECT time_bucket(NULL, time), count(*)
FROM metrics
GROUP BY 1;

Fixed it by raising an ERROR if a NULL bucked_width is used during the Continuous Aggregate query validation.

When creating a Continuous Aggregate using a NULL `bucket_width` in the
`time_bucket` function it lead to a segfault, for example:

CREATE MATERIALIZED VIEW cagg WITH (timescaledb.continuous) AS
SELECT time_bucket(NULL, time), count(*)
FROM metrics
GROUP BY 1;

Fixed it by raising an ERROR if a NULL `bucked_width` is used during the
Continuous Aggregate query validation.

jnidzwetzki added a commit that referenced this pull request Nov 27, 2023
This release contains performance improvements, an improved hypertable DDL API
and bug fixes since the 2.12.2 release. We recommend that you upgrade at the next
available opportunity.

In addition, it includes these noteworthy features:

* Full PostgreSQL 16 support for all existing features
* Vectorized aggregation execution for sum()
* Track chunk creation time used in retention/compression policies

**Deprecation notice: Multi-node support**
TimescaleDB 2.13 is the last version that will include multi-node support. Multi-node
support in 2.13 is available for PostgreSQL 13, 14 and 15. Learn more about it
[here](docs/MultiNodeDeprecation.md).

If you want to migrate from multi-node TimescaleDB to single-node TimescaleDB read the
[migration documentation](https://docs.timescale.com/migrate/latest/multi-node-to-timescale-service/).

**PostgreSQL 13 deprecation announcement**
We will continue supporting PostgreSQL 13 until April 2024. Sooner to that time, we will
announce the specific version of TimescaleDB in which PostgreSQL 13 support will not be
included going forward.

**Starting from TimescaleDB 2.13.0**
* No Amazon Machine Images (AMI) are published. If you previously used AMI, please
use another [installation method](https://docs.timescale.com/self-hosted/latest/install/)
* Continuous Aggregates are materialized only (non-realtime) by default

**Features**
* #5575 Add chunk-wise sorted paths for compressed chunks
* #5761 Simplify hypertable DDL API
* #5890 Reduce WAL activity by freezing compressed tuples immediately

* #6062 Add metadata for chunk creation time
* #6077 Make Continous Aggregates materialized only (non-realtime) by default
* #6177 Change show_chunks/drop_chunks using chunk creation time
* #6178 Show batches/tuples decompressed during DML operations in EXPLAIN output
* #6185 Keep track of catalog version
* #6227 Use creation time in retention/compression policy
* #6307 Add SQL function cagg_validate_query

**Bugfixes**
* #6188 Add GUC for setting background worker log level
* #6222 Allow enabling compression on hypertable with unique expression index
* #6240 Check if worker registration succeeded
* #6254 Fix exception detail passing in compression_policy_execute
* #6264 Fix missing bms_del_member result assignment
* #6275 Fix negative bitmapset member not allowed in compression
* #6280 Potential data loss when compressing a table with a partial index that matches compression order.
* #6289 Add support for startup chunk exclusion with aggs
* #6290 Repair relacl on upgrade
* #6297 Fix segfault when creating a cagg using a NULL width in time bucket function
* #6305 Make timescaledb_functions.makeaclitem strict
