PostgreSQL® extensions you need to know in 2025

The PostgreSQL extensions ecosystem is a vital feature of the database, enabling it to adapt to modern data use cases such as AI, analytics, and document data stores. This flexibility keeps PostgreSQL viable for businesses and startups, making it easier to "outgrow" the database. The ecosystem allows developers to deploy extension code on a running PostgreSQL database with ease, but there are risks involved due to the open-source nature of the extensions. To mitigate these risks, using a managed service like Aiven can provide quality vetting and automatic backups. Some notable extensions include TimescaleDB for time-series data, PostGIS for geospatial objects, and pgvector for AI and ML applications. The PostgreSQL community is at a crossroads, balancing wide adoption with the need for reliable maintenance and management, and Aiven is eager to see how this plays out.
