Complete Walkthrough: Running ElizaOS with PostgreSQL and Exporting the Schema

This step-by-step guide will walk you through the process of configuring ElizaOS to use PostgreSQL instead of its default embedded database, and then exporting the database schema for analysis or documentation purposes.

Prerequisites

Before starting, ensure you have the following:

ElizaOS installed (repo cloned)
PostgreSQL installed on your system

Quick Start Guide

# Clone repo
git clone https://github.com/HKUDS/lightrag.git
cd lightrag

# Set up environment

pip install python-dotenv anthropic set ANTHROPIC_API_KEY your-api-key-here

from anthropic import Anthropic
from dotenv import load_dotenv
import os

# Load environment variables
load_dotenv()

	function rustr
	if test (count $argv) -ne 1
	echo "Usage: rustr <filename>"
	return 1
	end

	set filename $argv[1]
	set output_file (string replace -r '\.rs$' '' $filename)

	# Create the build directory if it doesn't exist

	import param as pm
	import pandas as pd

	def serialize_param(obj: pm.Parameterized, skip_dataframes=True, exclude_params=None):
	"""
	Recursively serialize a Parameterized object into a nested dictionary.

	Parameters:
	- obj: pm.Parameterized
	The object to serialize.

	import holoviews as hv
	hv.extension('bokeh')

	import pandas as pd

	nodes = [
	{
	'name': 'A',
	'x': 1,
	'y': 0.5,

	import pandas as pd
	import holoviews as hv
	import hvplot.pandas
	hv.Points((1,1)).opts(size=10) * hv.Points((2,2)).opts(size=10) * pd.DataFrame([[1,1],[2,2]]).hvplot.line(x='0',y='1')
