PostgreSQL DDL redesigns, ClickHouse view security, TOAST and kubelet work

PostgreSQL developers debated DDL helper redesigns and reviewed TOAST, temporal, and aggregate patches while ClickHouse hardened view security barriers. Kubernetes and QEMU threads examined static kubelet builds, a Xen regression, and TCG lock changes.

PostgreSQL pg_get_*_ddl redesign debate

Core hackers on pgsql-hackers disputed redesign or removal of pg_get_role_ddl() over dependency ordering, password handling, and pg_dump duplication. The heated 25-message thread involved 8 participants. Maintainers of schema tools and dump utilities should watch for API or behavioral shifts.

ClickHouse DEFINER view security fixes

A ClickHouse GitHub thread detailed fixes for security barriers in DEFINER and NONE views against additional_table_filters and row-policy predicate pushdown. Two participants exchanged 29 technical messages. Operators relying on view-based access controls and row policies have direct interest in the hardening.

8-byte TOAST values patch review

PostgreSQL hackers actively reviewed a v16/v17 patch adding 8-byte TOAST pointers and Oid8 support via a new reloption. The 37-message discussion drew 8 participants. Storage-heavy workloads that toast large values stand to gain from expanded pointer range.

Kubernetes static kubelet binary proposal

The Kubernetes development list discussed a PR to build kubelet with CGO_ENABLED=0 and sought input on DNS and NSS resolver changes. Seven participants contributed 13 messages. Static builds can simplify packaging in environments that limit dynamic linking.

FOR PORTION OF concurrency review

Andres Freund reviewed the FOR PORTION OF patch and flagged concurrency bugs in READ COMMITTED plus trigger and DELETE issues. Four participants exchanged 9 messages on pgsql-hackers. Temporal query support needs these corrections before wider use.

QEMU Xen hotplug regression and list policy

A Xen hotplug regression report on features published after InitWait since commit 240cc11369fc pivoted into a heated qemu-devel debate over mailing-list policy banning LLM-generated text. Four participants sent 9 messages. The policy discussion may alter contribution norms on the list.

PostgreSQL PRODUCT() aggregate review

Postgres hackers reviewed a PRODUCT() aggregate patch, focusing on performance, overflow, and SQL-standard ON EMPTY syntax. Five participants discussed it across 19 messages. Analytic workloads that multiply values could gain a native aggregate.

QEMU TCG BQL pushdown series

A QEMU TCG series pushed the BQL into per-target do_interrupt handlers to cut contention and received multiple Reviewed-by tags from maintainers. Five participants handled 24 messages on the 11-patch v3 series. Reduced lock contention benefits multi-target emulation performance.
