dev environment postgres health check emitting errors

[gsnider2195]

Environment

• Nautobot version (Docker tag too if applicable): v1.5.12
• Python version: v3.7
• Database platform, version: postgres
• Middleware(s):

Steps to Reproduce

1. run the development environment invoke debug using docker-compose.postgres.yml for the db container

Expected Behavior

No errors are emitted from the database container

Observed Behavior

Database container logs the following messages

nautobot-db-1             | 2023-03-14 17:08:43.726 UTC [87] FATAL:  role "root" does not exist
nautobot-db-1             | 2023-03-14 17:08:48.800 UTC [96] FATAL:  role "root" does not exist
nautobot-db-1             | 2023-03-14 17:08:53.875 UTC [105] FATAL:  role "root" does not exist

Adding PGUSER=nautobot to the db container environment fixes this.

    healthcheck:
      test: pg_isready --username=$$POSTGRES_USER --dbname=$$POSTGRES_DB
      interval: 5s
      timeout: 5s
      retries: 15
      start_period: 300s  # In case DB needs recovery, allow 5 mins of failures
