This document describes how to configure PostgreSQL for Miniflux.

Database Installation ¶

The first step is to install PostgreSQL with your package manager.

For example, on Debian it’s simple as typing this command:

sudo apt install postgresql postgresql-contrib

Database Configuration ¶

Here an example from the command line:

# Switch to the postgres user
$ sudo -u postgres -i

# Create a database user for Miniflux
$ createuser -P miniflux
Enter password for new role: ******
Enter it again: ******

# Create a database for miniflux that belongs to our user
$ createdb -O miniflux miniflux

# Create the extension hstore as superuser
$ psql miniflux -c 'create extension hstore'
CREATE EXTENSION

Enabling HSTORE extension for Postgresql

Creating Postgresql extensions requires the SUPERUSER privilege. Several solutions are available:

1. Give SUPERUSER privileges to the miniflux user only during the schema migration:

ALTER USER miniflux WITH SUPERUSER;
-- Run the migrations (miniflux -migrate)
ALTER USER miniflux WITH NOSUPERUSER;

2. You could create the hstore extension with another user that have the SUPERUSER privileges before running the migrations.

sudo -u postgres psql $MINIFLUX_DATABASE
> CREATE EXTENSION hstore;

Note that if you use Debian or Ubuntu, you might have to install the postgresql-contrib package to activate the HSTORE extension.

Recent versions of Miniflux non longer uses the HSTORE extension but it still required to run the SQL migrations.

Database Connection Parameters ¶

Miniflux uses the Golang library pq to communicate with PostgreSQL. The list of connection parameters are available on this page.

The default value for DATABASE_URL is user=postgres password=postgres dbname=miniflux2 sslmode=disable.

You could also use the URL format postgres://postgres:postgres@localhost/miniflux2?sslmode=disable.
