Struggling to pinpoint why your #PostgreSQL query is slow? EXPLAIN (ANALYZE, BUFFERS) gives the execution plan, but complex plans can hide performance clues. 🧠Plan visualizers save the day! What are your favorite tools for visualizing & optimizing Postgres query plans?

It's amazing that you can prompt for non-breaking optimization and learn something new every day. I still don't have to queue anything, but the performance lift by simplifying the queries and response payloads are more than enough to see the performance lift.

I wish more ZK and FHE people would give their overhead as a ratio (time to compute in-cryptography vs time to compute raw), rather than just saying "we can do N ops per second" It's more hardware-independent, and it gives a very informative number: how much efficiency am I…

Postgres just got even faster Like most databases, Postgres work with fixed size pages. Those pages are 8K in size, each page will have the rows, or index tuples and a fixed header. The pages are just bytes in files and they are read and cached in the buffer pool. If a table…

How PostgreSQL Works: Internal Architecture Explained 1. 𝐏𝐫𝐨𝐜𝐞𝐬𝐬-𝐁𝐚𝐬𝐞𝐝 𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞: PostgreSQL follows a process-per-connection architecture, meaning each client connection is handled by a dedicated operating system process. 2. 𝐖𝐫𝐢𝐭𝐞 𝐀𝐡𝐞𝐚𝐝…

This new PostgreSQL 17 feature is game changer. You see, postgres like most databases work with fixed size pages. Pretty much everything is in this format, indexes, table data, etc. Those pages are 8K in size, each page will have the rows, or index tuples and a fixed header. The…
