In Record complex data coming as string

• asyncpg version: 0.20.1
• PostgreSQL version: "version" (using select version()
  "PostgreSQL 12.2 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39), 64-bit"
• Do you use a PostgreSQL SaaS? If so, which? Can you reproduce
  the issue with a local PostgreSQL install?: Using installed version on a GCP server not Saas
• Python version: 3.8.2
• Platform: CentOS8
• Do you use pgbouncer?: No
• Did you install asyncpg with pip?: Yes
• If you built asyncpg locally, which version of Cython did you use?: NA
• Can the issue be reproduced under both asyncio and
  uvloop?: Yes

Following is my asyncpg code for fetching data:

 conn = await asyncpg.connect(
                user,
                password,
                database,
                host,
                port,
            )
            records = await conn.fetch(query)
            values = [dict(record) for record in records]
            return values

record result that is received contains a complex object in the form of string as follows:

'Affinity':'{"Quantity" : 0, "Revenue" : 0, "Margin" : 0, "Adjustable_Quantity" : 0, "Adjustable_Revenue" : 0, "Adjustable_Margin" : 0}'

Due to which there's extra parsing required to convert data from string to object. Is it possible to not get the data as string by default, like other adapters psycopg2 provide. Please recommend a workaround otherwise this needs lots of code addition to parse each and every object. I would ideally expect caller to directly consume json objects instead of parse and consume

El issue no proporciona ningún archivo del repositorio ni ninguna prueba; comienza en la llamada conn.fetch(query) y la conversión mediante dict(record), usando el valor mostrado, similar a JSON, como caso de reproducción. Comprueba cómo devuelve asyncpg este valor de PostgreSQL y determina el tipo de resultado predeterminado esperado. Se considera terminado cuando el comportamiento deseado del objeto está especificado y cubierto por una prueba de regresión.
