Looks to me there are some maintenance tasks running. These tasks include auto-vacuum processes, log rotations, and other routine system maintenance activities that run automatically to optimize database performance and ensure data integrity. Even without any user-initiated connections or operations, these background processes can generate logs and temporary files, gradually consuming storage space.
