"Explicit select list" would be one way (and the one that's
encouraged as good practice):
select col1, colx, col2, col3 from tx;
If that doesn't cut it (say, generic viewer which doesn't
know what is going to be viewed) - use a view over tx. Maybe
even "hide" the table tx as "table_tx" and name the view
itself "tx". Care needs to be taken then to either setup
appropriate rules or to make insert/update/delete go to
"table_tx".
