Spoke at @PGConfIndia on using #PostgreSQL + vectors to find the best coffee ☕. Big thanks to @clairegiordano for the shout out & everyone for the great energy! Also, yes, caffeine levels were high. 😆 @AzureDBPostgres #PostGIS #VectorSearch

[Claire Giordano ✨ @clairegiordano]

On the big ballroom stage at @PGConfIndia in Bengaluru is @iVarund from the @AzureDBPostgres team giving his talk about “Using Postgres to locate the best coffee near you!”

And to teach us about how to use #PostgreSQL with vectors for semantic search, Varun used data about local coffeeshops, a local delivery service called Zomato, a cameo by Dora the Explorer, vector comparisons by @pamelafox … and apparently Varun himself had several (!!) coffees before getting up on stage. All in all a quite good session with a ton of audience involvement.

AI apps need more than transactions—they need databases built for reasoning.

At #MSBuild, see how Azure Databases power AI directly in the database layer, simplifying your stack and enabling real-time intelligence. Plus, get a look at building AI apps with #AzureHorizonDB.

Nice episode from @clairegiordano with @luiginardi - enjoyed hearing the #DBtune story and why they went with Postgres. 🎙️

[Claire Giordano ✨ @clairegiordano]

🎙️ New #TalkingPostgres #podcast Ep35 is out!

Luigi Nardi, the founder of an automated database tuning startup, joined to dig into how he got started with DBtune & why they chose PostgreSQL

@sjivan @AzureDBPostgres Thanks for raising this @sjivan - interesting extension and use case.
It would be great if you could also log this on the Azure PostgreSQL Feedback Forum (https://t.co/W4NyLMIKct) with a brief scenario on how you’d use 'pg_textsearch'. That helps us prioritize.
