Description

Hi! I'm using asyncpg 0.30.0 with python 3.12 and faced strange behaviour of jsonb, my db row contains something like [] or [{},...,{}] and most of it is arrays contains jsons in array.
But some times in records without any items i get '[]' and sometimes [].

Anybody have same issue?

Research direction

No file or test is named. Start by reproducing the differing [] and '[]' results with asyncpg 0.30.0 and Python 3.12, then trace the JSONB handling entry point. Done means identifying whether the behavior is in asyncpg or outside it and, if confirmed, adding focused regression coverage.
