Patch lines.

A proposed AI-assisted review pipeline for a small CommitFest queue: reproducible builds, red-green tests, adversarial reviews, and public summaries linked to the evidence. Designed to help human reviewers, not replace committer judgment.

Low-overhead core timing, trace capture, coverage analysis, independent observer-effect benchmarks, and honest query/plan-node attribution.

blocker: Needs more reviewer cycles, benchmark scrutiny, and a clear relationship with the separate EXPLAIN wait-event series.

Expose cumulative server-message counts by backend, database, user, severity, and SQLSTATE without parsing log files.

blocker: The new contrib patch needs independent overhead, contention, and cardinality review plus agreement on contrib versus core placement.

Reduce shutdown latency and turn binary replacement, release-note remediation, and extension compatibility into a repeatable fleet workflow.

blocker: Adaptive checkpointing and cache handoff are design ideas without bounded benchmarks or a fail-closed compatibility protocol yet.

Log the correct commit-record LSN for DROP TABLE and related destructive operations to make PITR recovery less guessy.

blocker: The corrected PR changes have not yet been posted back to -hackers and CommitFest.

Keep logical slots usable on a standby fed by WAL archives by pausing and safely resuming recovery around conflicts.

blocker: Crash-safety and promotion behavior need complete end-to-end coverage before upstream submission.

Inspired by the October 29 Hacking Postgres session, viewer Adam Brusselback implemented WHERE support for targeted REFRESH MATERIALIZED VIEW and has continued revising it through review.

blocker: The current patch has acknowledged privilege-escalation and error-cleanup bugs; the next revision has not been posted yet.

Compress or batch larger WAL records, originating in B-tree build experiments.

blocker: Closed CommitFest entry is waiting on the author.

Negotiate custom command-completion tags through a _pq_ protocol capability.

blocker: No CommitFest entry and the protocol design needs broader consensus.

Salma El-Sayed’s implementation, mentored by Kirk Wolak, merges sparse siblings and reclaims merged-away tombstone pages without rebuilding the entire index.

blocker: The October 14 testing campaign reports wrong results, cleanup and validation problems, and standby safety failures in the prototype. Reproduce against exact revisions, land focused fixes, and retest before benchmarking or readiness claims.

Keep loadable slots for excluded table data so replacement data is restored before dependent indexes and constraints.

blocker: The patch needs a filter-file-oriented interface revision and another version.

Dmitry’s pg_wait_tracer and core wait-event timing work, supported here with design sessions, reviews, coverage analysis, and independent benchmarks.

A proposed GSoC project that continued independently: systematically identify invisible waits and add coverage, starting with blocking writes to server logging destinations.

Quan continued the proposed GSoC work on LWLock contention. In parallel, an AWS-led patch series implements a broader pgstat-based redesign for the same scalability problem.

Fix standby MultiXact creation and deadlock/corruption edge cases.
