Everyone's excited about repack in Postgres! Curious about the graph queries too. Lots of goodies in Pg19. ⬇️
Postgres 19 is almost here, and whew it's packed with awesome! - REPACK CONCURRENTLY! - Graph queries - Partitioning improvements - COPY, SQL, and planner improvements - Logical rep improvements A deep dive on the @Snowflake blog - snowflake.com/en/blog/engine…
Q&A about Postgres Async i/o today. Join us! meetup.com/postgres-meetu… (we'll record it too)
@fwiles @KatiMichel Any member can invite anyone else. @KatiMichel is honorary LFK now, I just invited her😀
New ❄️🐘 blog! Cypher graphs in Postgres with the Apache Age extension snowflake.com/en/blog/engine…
Every company wants to "do #openSource." Few have a strategy for it. Sp I started writing about that: opensourceonpurpose.substack.com
@drishtijjain @ycombinator 🙌 Congrats!!!
@glcst What a great story! 💕
@crunchydata pg_stat_statements is the first thing I turn on in any new Postgres deployment. Paired with auto_explain it tells you exactly which queries burn your IO budget. Perf debugging goes from hours to minutes.
Your Postgres is 100x slower than traditional OLAP engines. A deceptively simple OSS extension fixes this. Here's an interview where we dive into the deep engineering around how this is achieved. Joining me (and leading the conversation) is Marco Slot: an engineer with an EXTENSIVE and impressive career history around PostgreSQL: 👉 Created pg_cron in 2017 (3.7k stars) - a tool to run cron-jobs in Postgres 👉 Built pg_incremental - fast, reliable, incremental batch processing inside PostgreSQL itself 👉 co-created pg_lake (after working on Crunchy Data's Warehouse, and getting acquired into Snowflake) 👉 Helped get pg_documentdb (MongoDB-on-Postgres) off the ground @marcoslot is a world-class expert in Postgres extensions. He seriously impressed me with his knowledge over the course of a private LinkedIn conversation, and now that I type out his resume - I understand where it came from. He should be on everyone's radar. So I brought him on the pod. In our full 2-hour deep-dive, we went over: • 🔥 how pg_lake makes analytics 100x faster (literally) • 🔥 perf internals like vectorized execution & CPU branching • 🤔 practical differences between OLTP and OLAP database development (and the age-old mission in uniting both) • 🤔 how (and why) pg_lake intercepts query plans and delegates parts of the query tree to DuckDB • 💡 why Postgres is architecturally terrible at analytical queries (and how vectorized execution fixes this) • 💡 Marco's hard-won experience through a decade+ career in Postgres • 🏆 Iceberg's role as the TCP/IP for tables • 🏆 what the real moat of PostgreSQL is Developments like pg_lake are a real reason why "Just Use Postgres" is much more than a meme, and it'll continue to dominate discourse. I promise you will learn a lot from this episode. Timestamps: (0:02) What is pg_lake? (2:23) Postgres' 100x slower problem and columnar storage experiments they had to make Postgres fast for analytics (6:00) practical examples and internals (16:20) perf internals - vectorized execution & CPU optimization (23:00) pg_lake architecture (why DuckDB isn't embedded) and the connection-per-process issue (29:16) how pg_lake intercepts the query plan tree and delegates parts to DuckDB (41:09) Iceberg catalogs (48:24) postgres to iceberg ingestion patterns (and pg_incremental) (53:40) Marco's (long) career: early AWS, Citus, Microsoft, Crunchy Data & Snowflake (1:04:20) Marco's observations around the merging between OLTP and OLAP (and the subtle dev differences there) (1:15:30) reverse ETL (1:33:08) Iceberg as the TCP/IP for tables (1:35:00) Marco's thoughts on the "Just Use Postgres" fever

@KatiMichel I saw Bill Self today around the block from my house getting pizza!
@brandur Well we have to have something to wait for so we can check on all the other work Claude is doing for us. 😂Between CI and AI ... we're just the middle man pressing the return button and waiting.
This is 11/10 today for April Fools in OpenSource given the Anthropic news ... 💀🤣
BREAKING: Entire Grafana codebase leaked. github.com/grafana/grafana
Hey - there's now fully open source and reusable #Postgres training materials. Teach. The. Kid. 🙌 github.com/Snowflake-Labs…
Some of favorite Postgres features use sub select logic so we made a small matrix to these tools, when you use them, and some simple SQL examples. We know you'll probably have Claude (or another LLM) write your SQL now but you should at least know what to ask for 😜 .
Excited for Postgres Meetup for All Wednesday to talk about Vibe Coding with Postgres. Join us! meetup.com/postgres-meetu…
