# Postgres extension marketplaces

> Postgres is now the AI database. The extension ecosystem is the next platform.

**Sector**: [Data Infrastructure](https://signals.gitdealflow.com/niche-down/data-infrastructure)  
**Build cost**: Team-sized build  
**Deal velocity**: Steady — one deal per month

## Why now

Postgres extensions (pgvector, pg_cron, pg_search) are exploding. The discovery + install layer is unbuilt.

## What the signal looks like

Repos with extension installers, multi-version Postgres support, and CI for extension testing.

## Public examples

*Public projects + categories only — we never name founders tracked inside the paid product.*

- Supabase + extensions
- Neon + branching
- Tembo-style Postgres marketplaces

## What this displaces

A Stack Overflow answer from 2019.

## Our build-vs-invest call

Strategic moat — the Postgres distro that ships the right extension bundle wins the AI workload.

## Frequently asked

### Buyer?
