!    A policy limits the ability to SELECT, INSERT, UPDATE, or DELETE rows
!    in a table to those rows which match the relevant policy expression.
!    Existing table rows are checked against the expression specified via
!    USING, while new rows that would be created via INSERT or UPDATE are
!    checked against the expression specified via WITH CHECK.  Generally,
!    the system will enforce filter conditions imposed using security
!    policies prior to qualifications that appear in the query itself, in
!    order to the prevent the inadvertent exposure of the protected data to
!    user-defined functions which might not be trustworthy.  However,
!    functions and operators marked by the system (or the system
!    administrator) as LEAKPROOF may be evaluated before policy
!    expressions, as they are assumed to be trustworthy.

!    A policy permits SELECT, INSERT, UPDATE or DELETE commands to access rows
!    in a table that has row level security enabled.  Access to existing table
!    rows is granted if they match a policy expression specified via USING,
!    while new rows that would be created via INSERT or UPDATE are checked
!    against policy expressions specified via WITH CHECK.  For policy
!    expressions specified via USING which grant access to existing rows, the
!    system will generally test the policy expressions prior to any
!    qualifications that appear in the query itself, in order to the prevent the
!    inadvertent exposure of the protected data to user-defined functions which
!    might not be trustworthy.  However, functions and operators marked by the
