PostgreSQL 15 introduced the MERGE command, which fails to test new rows against row security policies defined for UPDATE and SELECT . If UPDATE and SELECT policies forbid some row that INSERT policies do not forbid, a user could store such rows. Subsequent consequences are application-dependent. This affects only databases that have used CREATE POLICY to define a row security policy.
The PostgreSQL project thanks Dean Rasheed for reporting this problem.
