In this talk we'll review Row-Level Security (RLS), provide examples and use-cases, discuss the work which has been done on adding Row Level Security to PostgreSQL and the current state of that effort. PostgreSQL has long had a complex and interesting set of permissions available through the GRANT system. There is another system which exists in many other RDBMS's known as row-level security (RLS), where the rows returned is filtered based on a policy implemented on the table.
