Deploy and Host Supabase Postgres on Railway

Supabase Postgres is a production-hardened PostgreSQL image packed with 50+ extensions including PostGIS, pgvector, pg_cron, and pgjwt. It includes optimized configurations, security defaults, and popular extensions pre-installed, eliminating the setup overhead of vanilla Postgres while maintaining full PostgreSQL compatibility.

About Hosting Supabase Postgres

Deploying Supabase Postgres gives you an enterprise-grade PostgreSQL setup without manual extension compilation, configuration tuning, or custom dockerfiles to maintain.

The image includes extensions for

• geospatial data (PostGIS)
• vector similarity search (pgvector)
• time-series data (TimescaleDB)
• job scheduling (pg_cron)
• authentication (pgjwt).
• auditing (pg_audit)
• and even more :tm:

It comes pre-configured with sensible memory settings, connection pooling parameters, and logging options as well.

Railway handles persistent volume mounting, automated backups (if you're on the pro plan or above), and network configuration, so you get a production-ready database in one click instead of spending hours or days on setup.

Common Use Cases

• AI/ML Applications: Built-in pgvector extension for storing and querying embeddings, perfect for RAG pipelines, semantic search, and recommendation systems
• Geospatial Applications: PostGIS support for location-based services, mapping applications, and spatial data analysis
• Full-Stack Applications: Drop-in PostgreSQL replacement with enhanced capabilities for Next.js, React, or any web framework requiring a robust database
• Real-time Applications: Logical replication and pub/sub capabilities for building real-time features, webhooks, and event-driven architectures
• Multi-tenant SaaS: Row-level security (RLS) policies and JWT authentication extensions for building secure multi-tenant applications

Dependencies for Supabase Postgres Hosting

None! works out of the box with Railway. Just bring your app or favourite database client along.

Deployment Dependencies

Supabase Postgres Docker Image - Official source repository PostgreSQL Documentation - Complete PostgreSQL reference pgvector Documentation - Vector similarity search extension PostGIS Documentation - Geospatial extension reference

Implementation Details

Here are a few useful snippets you might want when getting setup.

Connecting to your database

Since this is based on the PostgreSQL image all the baseline Railway postgres features should work including the integrated extensions tool, database viewer, etc. I've also kept the Railway conventions around public/private database URLs you can reference in other services

Enabling specific extensions

not all extensions come enabled by default; you can enable common ones with the commands below:

-- Enable vector similarity search
CREATE EXTENSION IF NOT EXISTS vector;

-- Enable geospatial capabilities
CREATE EXTENSION IF NOT EXISTS postgis;

-- Enable HTTP requests from PostgreSQL
CREATE EXTENSION IF NOT EXISTS http;

-- Enable scheduled jobs
CREATE EXTENSION IF NOT EXISTS pg_cron;

Viewing the available extensions

If you want to see all of the available extensions, you can do so with this query.

SELECT * FROM pg_available_extensions ORDER BY name;
