Fix information leakage in constraint-violation error messages
(Heikki Linnakangas)
</para>
<para>
If an <command>UPDATE</command> command attempts to move a row to a
different partition but finds that it violates some constraint on
the new partition, and the columns in that partition are in
different physical positions than in the parent table, the error
message could reveal the contents of columns that the user does not
have <literal>SELECT</literal> privilege on.
