## What it is
aiopg is a Python library for accessing PostgreSQL databases from asyncio applications, wrapping the asynchronous features of the Psycopg driver. It provides connection pooling, async cursors, and optional SQLAlchemy Core integration via aiopg.sa.

## Use cases
- query postgres from an asyncio application
- async postgres connection pool in python
- use sqlalchemy core with asyncio and postgres
- run non-blocking database queries in aiohttp web app
- listen to postgres notifications asynchronously
- migrate blocking psycopg code to asyncio

## When to choose
- you need asynchronous PostgreSQL access in an asyncio-based Python app
- you want connection pooling with async/await syntax
- you use SQLAlchemy Core expressions with async execution
- you need LISTEN/NOTIFY support without blocking the event loop

## When to avoid
- you use async frameworks built on asyncpg-style APIs and want maximum raw performance (consider asyncpg)
- you need full async SQLAlchemy ORM sessions (use SQLAlchemy's native asyncio support instead)
- your application is synchronous/threaded and doesn't use asyncio
- you target databases other than PostgreSQL
