Does this error have any implications related to database user permissions, and if so, how?

While 'relation does not exist' directly refers to the absence of the object, insufficient user permissions *can* sometimes contribute to the issue. Specifically, if the database user connecting does not have `USAGE` privilege on the schema where the 'users' table resides, they might not be able to 'see' or access the table, effectively making it appear as if it 'does not exist' for that user. However, a more direct permission error would typically manifest as 'permission denied for relation users'.
