# AI Dev Tool: Edge AI Vector Search API
# =======================================
# A production-ready API integration wrapper for PostgreSQL Vector Search Extension
# using FastAPI, Pydantic v2, and Cloudflare Workers

from fastapi import FastAPI, HTTPException
from pydantic import BaseModel
from typing import List, Optional
import psycopg2
import json
from cloudflare import WorkersKV

# Define the PostgreSQL database connection settings
POSTGRES_HOST = "localhost"
POSTGRES_PORT = 5432
POSTGRES_DB = "vector_search_db"
POSTGRES_USER = "vector_search_user"
POSTGRES_PASSWORD = "vector_search_password"

# Define the Cloudflare Workers KV namespace
WORKERS_KV_NAMESPACE = "vector_search_kv"

# Create a FastAPI app
app = FastAPI()

# Define a Pydantic model for vector search queries
class VectorSearchQuery(BaseModel):
    """Vector search query model"""
    query: str
    limit: Optional[int] = 10

# Define a Pydantic model for vector search results
class VectorSearchResult(BaseModel):
    """Vector search result model"""
    id: int
    score: float
    vector: List[float]

# Create a PostgreSQL database connection
