My database has a row
row1. ['userA', 'product', 'read']
I want to run function

addPolicies(
    ['userA', 'product', 'read'],
    ['userA', 'product', 'write']
)

I think the result should be
row1. ['userA', 'product', 'read']
row2. ['userA', 'product', 'write']
or

removePolicies(
    ['userA', 'product', 'read'],
    ['userA', 'product', 'write']
)

I think the result should be
no rows.

They're all return false
and database is not been effect

Is it intentional?
