How much RAM does PostgreSQL need?

Plan on 4 GB+ for typical use; add headroom if you expect many concurrent users.

Can I run other things on the same VPS?

Yes — size the plan so PostgreSQL plus your other workloads fit in RAM with room to spare.

Data

The advanced open-source relational database.

A battle-tested SQL database with rich features, extensions and strong durability, running on your own hardware.

Running your own PostgreSQL keeps your data under your control and avoids managed-database pricing that scales with usage.

1
Provision a VPS
Choose a plan with room for your data as well as the app.
2
Install the stack
Install Native packages or Docker.
3
Deploy the application
Follow the project’s official install guide for your distribution.
4
Enable HTTPS
Serve it on your own domain behind a reverse proxy with a certificate.
5
Back it up
Schedule a database dump plus a copy of any uploaded files to an off-box location.

Give PostgreSQL its own database user with rights only on its own schema.
Reverse-proxy PostgreSQL and terminate TLS at the proxy so certificates are managed in one place.
Take a VPS snapshot before major upgrades so you can roll back cleanly.
Keep PostgreSQL patched — most self-hosting incidents are unpatched software.
