This is basically what RLS does for you. You specify the access and you specify the current user(via a connection, SET ROLE, etc). Then it does all that complicated query filtering stuff for you, to ensure you don't screw it up.

Not really, the overhead is just different(and likely more of it) in your solution. It's not wrong nor is using RLS right.
