To start the server with PostgreSQL, you would: 1. First ensure PostgreSQL is properly set up 2. Set the database URL environment variable 3. Start the server as normal:
Copy code
bash
export PREFECT_API_DATABASE_CONNECTION_URL="<postgresql+asyncpg://user:password@hostname:5432/database_name>"
prefect server start --host 0.0.0.0 --port 4200
Would you like me to provide more specific details about setting up PostgreSQL for your environment?
