An error is now thrown only if the reference is actually fetched,

|
rather than whenever the enclosing expression is reached. For
|

|
example, many people have tried to do this in triggers:
|

|
<programlisting>
|

|
if TG_OP = 'INSERT' AND NEW.col1 = ... then
|
||||||
|
</programlisting>
|

This will now actually work as expected.
