How do you review code at the volume agents produce it? On the Claude Code team, once we had high coverage and deep reviews, we started optimizing for the minimum amount of human review time that doesn't raise reverts or incidents.

“We’re not ambitious enough” is easy to post and hard to follow. Here’s a practical tutorial, with prompts.

PostgreSQL in memory for testing. Contribute to shibukawa/pgmem development by creating an account on GitHub.

Real PostgreSQL 18 that runs in memory inside your tests. No Docker or disk; share read-only tests and isolate writes in milliseconds.

完全にオンメモリで動き、テストケースごとにフォークしてスケールするPostgreSQL「pgmem」を作りました。テストダブルの分類からアーキテクチャ、テスト用API、パフォーマンスまでを紹介します。

とにかく数多のサプライチェーンインシデントが発生しており、OSSを公開・頒布している身からすると、より気を使わなければいけない状況です。 例えば、配布しているバイナリやアーカイブ、パッケージなどの成果物(artifact)の信頼性を保証するために、それが、どのソースを元に、どの環境及びワークフローでビルドされたか…

Nothing is as fast as not doing anything. How Neki keeps great performance by only decoding the parts of a PostgreSQL result the router actually needs.

We take a look at some of the ways PostgreSQL rewrites your queries (or not).

Explore query plan hints in PostgreSQL 19. Learn how pg_plan_advice and pg_stash_advice work, when to use advice tags, and alternative tuning steps.

Two BM25 optimizations and benchmark configuration changes inspired by PlanetScale's TIN benchmarks make ParadeDB's text search faster without changing its document identifiers.

We had to upgrade our 56TB Aurora Postgres cluster by 31 July without taking Trigger.dev down. Instead of moving the database, we made the problem smaller: new runs and the control plane went to PlanetScale, and the old runs stayed behind.

A personal experiment: Apache Cloudberry, the most up-to-date open-source version of Greenplum, turned into a set of extensions for PostgreSQL 19. Plans are cut into slices, rows travel between segments, and transactions use distributed snapshots and two-phase commit, while PostgreSQL itself needed only 22 small patches that add new extension points.

ClickHouse Managed Postgres uses direct I/O and stripe-sized reads to keep backups fast while protecting the page cache and query latency.

PostgreSQL 19 comes with online table rewrites. Measured against pg_repack and pg_squeeze REPACK (CONCURRENTLY) is the fastest and the lightest on WAL under writes. Here's what it does to vacuum, readers, writers and old snapshots while it runs, and what to check before you start it.

How do Postgres providers handle a query that exhausts memory? A recursive query benchmark compares query failures and cluster survival across ClickHouse Managed Postgres, Cloud SQL, PlanetScale, and Amazon RDS.

In many real production databases, we often see some tables receiving high-frequency updates (millions per day) and autovacuum running repeatedly (hundreds of times per day). Additionally, those tables can sometimes become heavily bloated. The end effect is poor performance, poor concurrency, and an unmanageable database. In case we are using methods pg_gather for diagnosis, such … Continued

Use PostgreSQL ALTER FUNCTION SET work_mem to stop one function's sorts spilling to disk without a global change. A production fix: 150 GB a day to 0.
