Multiple databases

Multiple QuartDB instances can be used to connect to multiple databases, with an instance per database. Connections should then be managed explicitly with the auto_request_connection disabled, as so,

read_db = QuartDB(app, url=READ_DB_URL, auto_request_connection=False)
write_db = QuartDB(app, url=WRITE_DB_URL, auto_request_connection=False)

@app.get("/")
async def read():
    async with read_db.connection() as connection:
        await connection.execute("SELECT ...")

@app.post("/")
async def write():
    async with write_db.connection() as connection:
        await connection.execute("INSERT INTO ...")
