Usage

Usage is as easy as possible. Create new instance of ConnectionPool and start querying. You don't need to startup connection pool, the connection pool will create connections as needed.

from psqlpy import ConnectionPool, QueryResult


async def main() -> None:
    db_pool = ConnectionPool(
        username="postgres",
        password="pg_password",
        host="localhost",
        port=5432,
        db_name="postgres",
        max_db_pool_size=2,
    )

    async with db_pool.acquire() as conn:
        res: QueryResult = await conn.execute(
            "SELECT * FROM users",
        )

    print(res.result())
    db_pool.close()
