I just realized that I forgot to tag @clairegiordano.bsky.social and @aaronw.dev - the producers of this amazing podcast.

I'm so excited to go on Talking Postgres! One of my fav podcasts! I'll chat about my journey to found Nile and discover Postgres. The podcast has a Discord channel where fans discuss the episode as it is recorded. If you want to join ua live, let me know and I'll send you an invite.

The pgconf.dev 2026 schedule is stacked 🐘✨ WAL internals, query planning, logical replication, temporal data, columnar storage, 30 years of Postgres retrospective… and cake cutting. Something for every Postgres nerd. Full schedule → 2026.pgconf....

Poster sessions are honestly my favorite for complex deepdive topics. It is visual, conversational, collaborative and includes coffee. Just how I like my deep technical content.

PGConf.dev 2026: top things to do at the conference: • Debate MVCC trivia with strangers • Discover a feature you didn’t know you needed • Realize you’re not the only one who reads pg_waldump for fun Registration and CFP are open.

CFP for PGConf.dev 2026 is open until Jan 16 🐘 Tips for strong proposals: • Share what you discovered. Not just what you built. • Be specific • Discuss bigger Postgres picture • Failures welcome Be specific, connect to Postgres internals, and don’t hide the messy bits.

At what point do we stop saying “worth its weight in gold” and start saying “worth its weight in high-end GPU”?

So.. Pierre Barre just built an NFS server implementation on SlateDB. ZeroFS is today days old, but it's going to get wild. Bottomless storage and checkpoints mean instant FS snapshots (zero overhead). github.com/Barre/zerofs

Never mind. Looks like I remembered linear algebra wrong and matrices are strictly 2-dim.

Gwen Shapira @gwenshap.bsky.social · 30/05/2025
Why aren't these called Matrixes? Like multi-dimensional vectors were called back when I did linear algebra?

Gwen Shapira @gwenshap.bsky.social · 30/05/2025
So, Tensor (as in Pytorch) is just like a vector, except that it is somehow better for GPUs? Did I get that right?

I made a note to try this next time I have a problem query to debug :)

🛠️ Unused index debug flow: ANALYZE ➜ rethink predicate ➜ simplify query ➜ audit policies & GUCs ➜ If still wrong, try pg_hint_plan (force an index to prove a point) or hypopg (hypothetical indexes) before filing a bug.

Gwen Shapira @gwenshap.bsky.social · 29/05/2025
1️⃣ Stale stats: ANALYZE hasn’t run; filter looks un-selective. 2️⃣ Truly un-selective: Stats are right; scan really is cheaper. 3️⃣ Complex estimates: Many joins / ORs / CTE / functions scramble row estimates. 4️⃣ Handcuffs on: RLS limits optimizations or GUCs forbid the path. 5️⃣ Planner bugs: Rare but...

“Why is Postgres seq-scanning rather than use this index?” 🤯 Short answer: the planner thinks that index won’t help (or can’t use it). Longer answer—5 usual suspects 👇

🚨 New blog alert: Postgres 18 beta 1 was released last week, and includes native support for UUIDv7. Great opportunity to explain why UUIDv7 is a great fit for your database keys, and show you how to use them in PG18. www.thenile.dev/blog/uuidv7

So funny. When I was a kid in Israel, the game was known as "Hertzel amar". (Hertzel said, presumably after the legendary zionist leader).

You know the advice to say "thank you" instead of "sorry"? It looks like ChatGPT took it to heart. Me: You just said something incorrect. ChatGPT: Thank you for keeping it precise.

Preparing a presentation (this is a draft from early in the year, so probably preparing for Monster Scale). Looks like a mess, but IIRC, the result was actually good.
Very messy draft of a talk

Folks at Google: there's no longer a button to get the PDF of your research papers directly from your website. Instead you have to do a hop through Google Scholar. Is that intentional? Seems worse than it used to be before.
Screenshot of the Percolator paper on the Google Research website. There are buttons for "Google Scholar" and "Copy Bibtex", but none to download the actual paper!

Running TPC-C can be a bit challenging. Running pgbench is easy (it ships with Postgres and uses simple Postgres configs), but its main built-in script is TPC-B. Thankfully, Ryo Kanbayashi wrote a pgbench script that is TPC-C-like: github.com/ryogrid/tpcc...
