That's just exactly equivalent to
SELECT *
FROM (select *
from all_salaries
where user = CURRENT_USER
)
WHERE malicious_function(salary,employee)
Hm. If you incorrectly mark your function as IMMUTABLE even though it has side
effects then the planner may indeed collapse this. Does the planner know it
can't collapse views if the underlying tables aren't accessible to the user?
