@Marvin How do i set up Prefect with Postgresql without using Docker?

To set up Prefect with PostgreSQL without using Docker, you can follow these steps: 1. Install PostgreSQL: Make sure you have PostgreSQL installed on your system. You can install it using the official PostgreSQL downloads for your operating system. 2. Create a Database: Create a PostgreSQL database that Prefect will use. The default database name expected by Prefect is

prefect

. 3. Configuring Prefect to use PostgreSQL: - Set the

PREFECT_API_DATABASE_CONNECTION_URL

environment variable with your PostgreSQL connection details. Here's an example format for the environment variable:

export PREFECT_API_DATABASE_CONNECTION_URL="postgresql+asyncpg://<USERNAME>:<PASSWORD>@<HOST>:<PORT>/<DATABASE>"

Replace

<USERNAME>

,

<PASSWORD>

,

<HOST>

,

<PORT>

, and

<DATABASE>

with your own PostgreSQL credentials and details. Here's a provided example assuming standard credentials and local PostgreSQL setup:

export PREFECT_API_DATABASE_CONNECTION_URL="<postgresql+asyncpg://postgres:yourTopSecretPassword@localhost:5432/prefect>"

Make sure to replace

yourTopSecretPassword

with the actual password for your

postgres

user. For more details, you can refer to the Prefect documentation on hosting. Remember that the

postgresql+asyncpg

scheme is for asynchronous communication with PostgreSQL, which Prefect supports. If you're using synchronous libraries or tools that expect a synchronous connection, you would use a different URL scheme, like

postgresql://

. Keep in mind that if you choose to use PostgreSQL, you should also ensure you have the

pg_trgm

extension installed and enabled in your PostgreSQL instance, as Prefect uses this extension.
