What is asyncpg and how do I use it?

Asyncpg is a database interface library for PostgreSQL in Python, designed for asynchronous programming. It allows you to interact with PostgreSQL databases using async/await syntax.

Can you show me a simple example of connecting to a database?

Sure! Here's a basic example:

import asyncpg

async def main():
    conn = await asyncpg.connect(user='user', password='password', database='db', host='127.0.0.1')
    await conn.close()

How do I execute a query using asyncpg?

You can execute a query using the fetch or execute methods. For example:

rows = await conn.fetch('SELECT * FROM my_table')

What are some common errors I should be aware of?

Common errors include connection issues, syntax errors in SQL queries, and data type mismatches. Always check your connection parameters and query syntax.
