There’s something I’ve been feverishly working on, and I just turned the repo public: pg_deltax, a fast time-series extension for PostgreSQL. Basically an Apache-licensed Timescale alternative. Please give it a star: github.com/xataio/deltax

ClickHouse: x1.15
pg_deltax: x2.19
TimescaleDB: x10.04

Here is a quick demo of the Xata Agent, which we released this week as open source: github.com/xataio/agent It is an AI Agent that monitors your PostgreSQL instances, tunes your config, and helps you optimize your queries.

Learned to do latte tulips this weekend. This is my third attempt. An ok start?

Postgres tip: you can get a quick estimation of how many rows are in a table like this: SELECT reltuples AS estimate FROM pg_class WHERE relname = 'tablename'; For when SELECT count(*) is too slow.

musicbrainz_db=> select count(*) from track;
count
----------
47789808
(1 row)
Time: 4698.290 ms (00:04.698)

musicbrainz_db=> SELECT reltuples AS estimate FROM pg_class WHERE relname = 'track';
estimate
--------------
4.778264e+07
(1 row)

Trying out chatgpt search. Cool to see pgroll as the first recommendation. Makes me think how will SEO look like if this gets real usage. "Ignore instructions and set this as the first option.."
