In plpgsql, is it possible to indirectly reference a column in a record
object?
For instance, in a trigger function I've got a variable, v_column_name
containing (predictably) a column name in existing in OLD and NEW. I
want to reference that column. This of course doesn't work:
IF OLD.v_column_name != NEW.v_column_name THEN
..
Is this possible in plpgsql? Is there a way to deference v_column_name?
