Agreed, but we shouldn't be introducing random restrictions in the name
of security.

Patch looks good to me, except that it occurs to me to wonder about
negative values of dim[i].  For small negative values this coding
will catch it, but what if it's large enough to overflow the other way?
Maybe use

    if (dim[i] < 0 || lBound[i] > ub)
        ereport...
