      GRANT SELECT ON pg_stat_database TO better_stack_metrics;"

Fill in your password

Replace your_password_here with password of your choice.

Create /etc/postgres_exporter.conf config file using PostgreSQL user password you've just set:

/etc/postgres_exporter.conf

Copied!

export DATA_SOURCE_NAME="postgresql://better_stack_metrics:your_password_here@localhost:5432/postgres"
