Released: 6 October 2026
EDB Postgres AI for ClickHouse 26.8.15.10 is the first release of the 26.8 LTS. It updates the ClickHouse server from 26.3.22.7 and updates the Kubernetes operator, MCP server, and pg_stat_ch.
ClickHouse server
| Type | Description |
|---|---|
| Upstream merge | Updated to the open-source ClickHouse 26.8.15.10 LTS release, from 26.3.22.7. |
| Feature | Added Debian 13 (trixie) .deb packages for amd64, arm64, and ppc64el, published alongside the RPM packages. |
| Bug fix | Disabled sending crash reports and LOGICAL_ERROR exceptions to an external endpoint. The send_crash_reports configuration section is still accepted for compatibility with existing configuration files, but it no longer has any effect. |
Kubernetes operator
| Type | Description |
|---|---|
| Upstream merge | Updated to 0.27.4-2edb1, tracking upstream Altinity clickhouse-operator release-0.27.4, from 0.27.3. The EDB release adds no upstream changes. Images are tagged 0.27.4-2edb1 and the Helm chart is versioned 0.27.4+2edb1. |
| Bug fix | Updated google.golang.org/grpc to v1.84.0, golang.org/x/text to v0.42.0, and github.com/go-openapi/swag to v0.29.2 to address security vulnerabilities, including GHSA-2v4p-qf9q-27wj, GHSA-hrxh-6v49-42gf, and GHSA-vp52-pcj8-j9qc. |
| Bug fix | The Helm chart and the operator's default images now come from the production repository, docker.enterprisedb.com/clickhouse, so a default installation works with a production subscription. |
| Bug fix | The operator's default ClickHouse and Keeper image is now pinned to edb-clickhouse-server:26.3.22.7-1edb1 instead of latest, so the deployed ClickHouse version no longer changes without an operator release. |
MCP server
| Type | Description |
|---|---|
| Upstream merge | Synced to upstream v0.7.0, from v0.4.1. Highlights include connection caching, query cancellation, Host and Origin validation for HTTP and SSE, and named query parameters on run_query. Requires clickhouse-connect 1.x. See the upstream release notes for the full list of changes. |
| Feature | Added Debian 13 .deb packages for amd64 and arm64, published alongside the RPM packages. |
| Change | CLICKHOUSE_SECURE now accepts only true or false, and CLICKHOUSE_VERIFY accepts only true, false, or proxy. Other values fail at startup. |
pg_stat_ch
| Type | Description |
|---|---|
| Change | Repackaged as 0.4.0-1edb2. The upstream version remains pg_stat_ch 0.4.0. |
| Feature | Added Debian 12 (bookworm) and Debian 13 (trixie) .deb packages alongside the RPM packages. Debian 13 packages cover community PostgreSQL only. See Compatibility. |
| Bug fix | The background worker no longer registers or connects to postgres when the postmaster is started by pg_upgrade in -b mode. Previously, that open connection blocked the DROP DATABASE "postgres" step in pg_restore and caused every binary upgrade to fail when pg_stat_ch was in shared_preload_libraries. |
