An SRF will guarantee an execution order and work for security purposes,
but getting your function with side effects to run early would be rather
challenging. Somehow you would need to make the planner think the
function is fairly selective without it actually being that way and the
only way that I'm aware of to get the planner to consider a functions
selectivity is to index it. But how do you index the function without
knowing all of the values?
