# ClickHouse's long-term support line settles down as dbt-core opens the door to Exasol

ClickHouse shipped a dense run of LTS maintenance releases and a managed Postgres onboarding overhaul, while dbt-core's 2.0 preview added a full Exasol adapter and hardened its exported index against compile-only columns.

### ClickHouse's LTS lines get a coordinated sweep

ClickHouse spent the week doing what mature analytics engines do best: paying down maintenance debt across several long-term support branches at once, from [the newest LTS line](https://github.com/ClickHouse/ClickHouse/releases/tag/v26.8.1.2041-lts) down through [the previous stable branch](https://github.com/ClickHouse/ClickHouse/releases/tag/v26.3.26.3-lts), [its follow-on patches](https://github.com/ClickHouse/ClickHouse/releases/tag/v26.3.25.2-lts), [the midweek fixes](https://github.com/ClickHouse/ClickHouse/releases/tag/v26.3.24.4-lts), [an earlier maintenance cut](https://github.com/ClickHouse/ClickHouse/releases/tag/v26.3.23.7-lts), and [the oldest supported line](https://github.com/ClickHouse/ClickHouse/releases/tag/v25.8.33.6-lts), plus [the earliest patch of the run](https://github.com/ClickHouse/ClickHouse/releases/tag/v26.3.22.7-lts). The practical upshot for anyone running ClickHouse in production: no matter which LTS branch you're pinned to, there's a current patch available, and the fix cadence suggests the project is deliberately keeping every supported line within reach of the same bug fixes rather than forcing upgrades. If you're on a pinned LTS, this is the week to schedule a rolling patch — but expect the notes to be incremental rather than headline-grabbing.

### Managed Postgres gets a real onboarding path

For teams who use ClickHouse alongside operational Postgres, the [new getting started experience for ClickHouse Managed Postgres](https://clickhouse.com/blog/clickhouse-managed-postgres-onboarding) walks users through a four-step flow that goes from provisioning a cluster to querying operational data and running real-time analytics inside ClickHouse. It's a small thing on paper and a large one in practice: the hardest part of adopting a managed analytics service is usually the first hour, and a guided path from "I have a database" to "I have a dashboard" removes most of the reasons teams stall.

The week's other ClickHouse posts round out the ecosystem picture. The [.NET Driver's road from 1.0 to 1.3](https://clickhouse.com/blog/whats-new-clickhouse-net-driver-10-to-13) brought type-safe POCO workflows, extensible serialization, broader type coverage, and performance work, alongside official ecosystem integrations — meaning C# shops no longer have to hand-roll their mapping layer. More interesting for anyone who has ever been burned by a flaky test suite, [ClickGap](https://clickhouse.com/blog/clickgap-autonomous-qa-for-clickhouse) applies autonomous QA to merged ClickHouse changes: it executes reproducers, filters out false positives, and attributes regressions to specific commits. And on the broader Postgres front, [read-your-writes semantics via WAIT FOR](https://clickhouse.com/blog/postgresql-19-wait-for-read-your-writes) in PostgreSQL 19 lets individual reads block on a specific WAL position, which finally makes asynchronous replicas safe for the read-after-write patterns that analytics dashboards depend on.

### Tinybird rebalances query budgets, Dagster tidies orchestration

Tinybird [raised the default Query API and Pipe endpoint timeouts on paid plans](https://www.tinybird.co/docs/changelog/2026-08-28-august-week-four), tiering them at ten seconds on free, twenty on shared paid infrastructure, and thirty on dedicated infrastructure, with existing custom overrides left untouched. The same update added a `replica` column to `pipe_stats_rt`, so you can see which ClickHouse replica executed each query — genuinely useful when you're debugging why the same pipe is fast one minute and slow the next. Over in Dagster, [dynamic partitions can now be wiped and deleted in one action](https://github.com/dagster-io/dagster/releases/tag/1.13.20), which also clears the asset's degraded health status, and alert policies can now fire on successful code location deploys rather than only failures.

### dbt-core's 2.0 preview widens the adapter map

dbt-core's 2.0 development line landed a Phase 1 [Exasol adapter with a full macro bundle](https://github.com/dbt-labs/dbt-core/releases/tag/v2.0.0-dev.30) — connection and auth with TLS and timeout profiles, agate and seed type conversion including HASHTYPE, typed SQL literals, reserved-keyword auto-quoting, and materializations spanning table, view, incremental append/merge/delete+insert/microbatch, plus snapshots and model contracts. The same work introduced parse-safe views like `dbt.models` and `dbt.columns`, so querying an exported index can no longer silently surface a compile-only or never-populated column — a subtle correctness fix that will save warehouse teams a class of confusing empty results. It also hardens tarball extraction against symlink and hard-link attacks, includes invocation IDs in Databricks query comments, and fixes a log-format-file regression.
