TimescaleDB in 2024: Making Postgres Faster
If I had to summarize 2024 for Timescale, I’d call it the year of Postgres for AI. From game-changing open-source launches like pgvectorscale (a performance booster for large production vector workloads with PostgreSQL + pgvector) to pgai (which integrates Postgres with LLMs for AI app development), we pushed the boundaries of what developers can achieve with Postgres. But AI wasn’t the only story. TimescaleDB’s time-series capabilities also evolved dramatically during 2024, making Postgres even faster for real-time analytics.

Building a Semantic Search Engine with OpenAI, Go, and PostgreSQL (pgvector)
pgvector extension installed in PostgreSQL. (See pgvector’s GitHub page for installation instructions.)

Semantic Search Feature
pg-vector is the opposite. It's widely used and is a Postgres extension. When it comes to Postgres, I think of Supabase, which offers free usage. Supabase has pg-vector integrated, and activation is just a click away, making it a great choice.

Everyone Uses Postgres… But Why?
No matter whether we are talking about custom data types, another in-memory processes, or AI use cases, Postgres can be tuned to support new scenarios. When some new requirement comes into play, we don’t need to start from scratch but we just need to extend PostgreSQL with an extension. Postgres is ready for whatever the future brings.
