I maintain this and other Home Assistant add-ons in my free time: keeping up with upstream changes, HA changes, and testing on real hardware takes a lot of time (and some money). I use around 5-10 of my >110 addons so regularly I install test machines (and purchase some test services such as vpn) that I don't use myself to troubleshoot and improve the addons

If this add-on saves you time or makes your setup easier, I would be very grateful for your support!

About

PostgreSQL, often simply "Postgres", is an object-relational database management system (ORDBMS) with an emphasis on extensibility and standards-compliance. As a database server, its primary function is to store data, securely and supporting best practices, and retrieve it later, as requested by other software applications, be it those on the same computer or those running on another computer across a network (including the Internet). It can handle workloads ranging from small single-machine applications to large Internet-facing applications with many concurrent users. Recent versions also provide replication of the database itself for security and scalability.

This addon is based on the official image : https://hub.docker.com/_/postgres

Configuration

Postgres port is by default 5432 and is exposed to the host network. Default user: postgres, password: set by POSTGRES_PASSWORD

Options

Option	Type	Default	Description
`POSTGRES_PASSWORD`	password	`homeassistant`	Password for the postgres user
`POSTGRES_USER`	str		Optional custom username
`POSTGRES_DB`	str		Optional default database name
`POSTGRES_INITDB_ARGS`	str		Additional arguments to initdb
`POSTGRES_HOST_AUTH_METHOD`	str		Host authentication method

Example Configuration

POSTGRES_PASSWORD: "your-secure-password"
POSTGRES_USER: "myuser"
POSTGRES_DB: "mydatabase"
POSTGRES_INITDB_ARGS: "--encoding=UTF8 --lc-collate=C --lc-ctype=C"
POSTGRES_HOST_AUTH_METHOD: "md5"

For more information, check the official PostgreSQL image docs.

Custom Scripts and Environment Variables

This addon supports custom scripts and environment variables through the addon_config mapping:

Custom scripts: See Running Custom Scripts in Addons
env_vars option: Use the add-on env_vars option to pass extra environment variables (uppercase or lowercase names). See https://github.com/alexbelgium/hassio-addons/wiki/Add-Environment-variables-to-your-Addon-2 for details.

Configuration File: By default postgresql.conf is stored in /config/postgresql.conf accessible by other addons and Home Assistant. You can modify it using the File Editor addon. For better security, change CONFIG_LOCATION to /data/orig/postgresql.conf to make it accessible only to this addon.

Installation

The installation of this add-on is pretty straightforward and not different in comparison to installing any other add-on.

Add my add-ons repository to your home assistant instance (in supervisor addons store at top right, or click button below if you have configured my HA)
Install this add-on.
Click the Save button to store your configuration.
Set the add-on options to your preferences, at least POSTGRES_PASSWORD is required.
Start the add-on.
Check the logs of the add-on to see if everything went well.
Use any Postgres client to connect, e.g. to homeassistant.local:5432

Security

By default, Postgres will be reachable on the local network of your host system. To improve security, you can disable this behavior and make Postgres available only to other Add-ons within Home Assistant.

Configure all Add-ons that use Postgres to connect via the internal DNS name: db21ed7f-postgres:5432.
Go to Settings → Add-ons → Postgres 15 → Configuration, and under Network, remove port 5432 by clearing the text field.
Click Save and restart the Add-on.
Postgres is now only accessible from other Add-ons and no longer reachable from your local network (e.g., laptop, IoT devices, etc.).
