> As of <SPAN

column numbers, corresponding to the column's position in
<TT
CLASS="LITERAL"
>SELECT * FROM relname</TT
>. Previous versions interpreted the
numbers as physical column positions. There is a difference if any
column(s) to the left of the indicated column have been dropped during
the lifetime of the table.
