Released: 2 November 2026
EDB Postgres AI for ClickHouse® 26.3.58.5 updates the ClickHouse server, the Kubernetes operator, pg_stat_ch, and introduces pg_clickhouse as a tracked component.
ClickHouse® server
| Type | Description |
|---|---|
| Upstream merge | Updated to the open-source ClickHouse 26.3.58.5 LTS release, from 26.3.37.3. |
| Bug fix | Fixed pods crash-looping with Couldn't create necessary directory when a disk is added to the ClickHouse configuration before its volume is mounted. |
| Change | The default user is passwordless again, and the image uses the upstream entrypoint, which reads the CLICKHOUSE_* environment variables. |
| Change | Removed the ClickHouse Cloud password-reset hint, and its clickhouse.cloud link, from the authentication failure message for the default user. |
| Bug fix | Fixed Debian dependency pins and keeper and server package metadata so EDB packages install correctly with apt. |
| Bug fix | Fixed a startup failure on ppc64le under emulation, caused by the bundled libunwind corrupting callee-saved vector registers. |
Kubernetes operator
| Type | Description |
|---|---|
| Change | The operator's default ClickHouse and Keeper image is now edb-clickhouse-server:26.3.37.3-1edb2, from 26.3.22.7-1edb1. |
pg_stat_ch
| Type | Description |
|---|---|
| Feature | Added Debian .deb packages alongside the RPM packages. Debian 12 (bookworm) packages for EDB Postgres Extended Server and EDB Postgres Advanced Server aren't published for Postgres 18. See Compatibility and Known issues. |
