Fix BuildIndexValueDescription for expressions
In 804b6b6db4dcfc590a468e7be390738f9f7755fb we modified
BuildIndexValueDescription to pay attention to which columns are visible
to the user, but unfortunatley that commit neglected to consider indexes
which are built on expressions.
Handle error-reporting of violations of constraint indexes based on
expressions by not returning any detail when the user does not have
table-level SELECT rights.
Backpatch to 9.0, as the prior commit was.
Pointed out by Tom.
