How do I manage transactions in asyncpg?

To manage transactions in asyncpg, you can use the transaction() method. This allows you to execute multiple queries as a single unit of work.

Can you show me a code example?

Sure! Here's a simple example:

import asyncpg

async def run_transaction():
    conn = await asyncpg.connect(user='user', password='password', database='db', host='127.0.0.1')
    async with conn.transaction():
        await conn.execute('INSERT INTO table_name(column) VALUES($1)', value)
        await conn.execute('UPDATE table_name SET column=$1 WHERE condition', new_value)
    await conn.close()

What happens if one of the queries fails?

If one of the queries fails within a transaction, all changes made during that transaction will be rolled back, ensuring data integrity.
