docker run -d --name dev-postgres -e POSTGRES_PASSWORD=dev -p 5432:5432 postgres:16
Run a throwaway Postgres 16 container for dev
Starts Postgres 16 in a detached container named dev-postgres, with the password env var set and port 5432 published. The -d flag daemonizes it and -p maps the port. Connect with psql -h localhost -U postgres, and remove the container with docker rm -f dev-postgres when done.
