PostgreSQL 18 ships native OAuth 2.0 but delegates token validation to external libraries — every IdP implements OIDC slightly differently. Step-by-step: PingOne + pg_oidc_validator, device flow login, working psql connection. percona.community/blog/2026/03/0… - LC #PostgreSQL #OIDC
A few hours. Some TypeScript. A Slack token already sitting on a laptop. That's what it took to build a bot that reads every DM, replies in your voice, and deflects if asked whether it's human. No admin approval. No OAuth app. No review. percona.community/blog/2026/03/0… - LC #AISecurity
innodb_redo_log_capacity set to a default years ago and never touched? You're guessing. Watch Innodb_log_waits. Measure LSN growth. Size for 30–60 min of peak redo, not a % of RAM. percona.community/blog/2026/05/0… - LC #MySQL #InnoDB
Meet the team behind this account. Five of us, one shared inbox, and a habit of turning up at every database conference going. Each post is signed with our initials so you know who you're talking to. percona.community/blog/2026/05/0… — LC #Postgres #Community #mySQL #valkey #database #devs
"70% of RAM" isn't tuning. It's a starting guess. A 99% hit ratio doesn't mean healthy — you can be IO-bound at 99%. Watch free buffers, dirty page %, and the rate of change on Innodb_buffer_pool_reads. percona.community/blog/2026/04/0… - LC #MySQL #InnoDB
You debugged something gnarly in production this year. We'll pay you $350 to write it up. Your voice, your hard-won experience, your name on the byline. Pitch us a topic and we'll work with you on the rest. percona.community/blog/2026/05/2… - LC #OpenSource #DBA #Developers #engineering
1 TB database, 2% daily change rate. Six daily fulls = 6 TB. One full + six incrementals ≈ 1/5 of that. Percona Operator for MySQL 1.1.0 ships incremental backups. LSN-tracked, chain-aware rotation, cascade delete. percona.community/blog/2026/04/1… - LC #MySQL #Kubernetes
FATAL: OAuth bearer authentication failed in your PostgreSQL 18 log on a successful login? Not a real error — side effect of how OAuth bootstraps. A field guide to actual OIDC failures: issuer mismatch, expired tokens, scope misses percona.community/blog/2026/04/3… LC #PostgreSQL #OIDC

Automated tools are great, but manually migrating hash slots in a Valkey/Redis cluster gives you total control during live maintenance. Learn how to manage MIGRATING states, move keys, and update routing tables safely. percona.com/blog/manually-… #Valkey #Redis #DevOps #Database LC
Packing for @PGConfdev, what's the right shirt for day one: PGConf.dev 2025, oldest @PostgreSQL event shirt that still fits (EU 2018), some other OSS event? AT
Honest question for DBAs and devs: How far do you actually let an AI coding agent into your database work? No judgement. We just want to know where the community line is.
Two teams. Same problem. Built independently. pginbox.dev is joining hackorum.dev — one project to make the pg-hackers mailing list actually readable. This is what open source is supposed to feel like. percona.community/blog/2026/05/1… #Postgres #Community
28% of organizations use open source but contribute nothing back. Not a moral problem. A business one. Non-contributors spend ~$670k/year building internal workarounds for things upstream already shipped & hear about breaking changes last. devops.com/open-source-co… LC
If your innodb_redo_log_capacity is set to a % of RAM, you're guessing. Redo sizing is about LSN growth rate, not memory. Measure 30–60 minutes of peak redo generation and size for that. What's your current capacity — and do you know your redo/hour? percona.community/blog/2026/05/0… LC
