Postgres with docker-compose or Docker and pg_stat_statements enabled

pg_stat_statements is useful to gather performance information about queries so lets add it to our dockerized postgres database.

Using docker-compose

Using docker-compose we just need to add the following docker-compose.yaml:

docker-compose.yml

version: '3.5'

services:
  postgres:
    container_name: postgres_container
    image: postgres
    ports:
      - "5432:5432"
    volumes:
      - /var/lib/postgresql/data
    # used for query profiling, deactivate for enhanced performance
    command: postgres -c shared_preload_libraries=pg_stat_statements -c pg_stat_statements.track=all -c max_connections=200
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: thepassword

We simply start our Postgres database with docker-compose:
