Release 2.22.1 (#8717)

## 2.22.1 (2025-09-30)

This release contains performance improvements and bug fixes since the
[2.22.0](https://github.com/timescale/timescaledb/releases/tag/2.20.0)
release. We recommend that you upgrade at the next available
opportunity.

This release blocks the ability to leverage **concurrent refresh
policies** in **hierarchical continous aggregates**, as potential
deadlocks can occur. If you have [concurrent refresh
policies](https://docs.tigerdata.com/use-timescale/latest/continuous-aggregates/refresh-policies/#add-concurrent-refresh-policies)
in **hierarchical** continous aggregates, [please disable the
jobs](https://docs.tigerdata.com/api/latest/jobs-automation/alter_job/#samples),
as following:

```
SELECT alter_job("<job_id_of_concurrent_policy>", scheduled => false);
```

**Bugfixes**
* [#7766](#7766) Load OSM
extension in retention background worker to drop tiered chunks
* [#8550](#8550) Error in
gapfill with expressions over aggregates and groupby columns and
out-of-order columns

* [#8644](#8644) Fix

* [#8657](#8657) Fix

* [#8659](#8659) Don't
propagate `ALTER TABLE` commands to foreign data wrapper chunks
* [#8693](#8693) Compressed
index not chosen for `varchar` typed `segmentby` columns
* [#8707](#8707) Block
concurrent refresh policies for hierarchical continous aggregate due to
potential deadlocks
