The target list order must be exactly the same as

</listitem>
<listitem>
there are some unpleasant restrictions on how functions returning
composite types can be used. Briefly, when calling a function that
returns a row, we cannot retrieve the entire row. We must either
- project a single attribute out of the row or pass the entire row into
+ extract a single attribute out of the row or pass the entire row into
another function. (Trying to display the entire row value will yield
a meaningless number.) For example,
<programlisting>
-SELECT name(new_emp());
+SELECT (new_emp()).name;
</programlisting>
<screen>
name
------
None
+</screen>
+
+ We need the extra parentheses to keep the parser from getting confused:
+
+<screen>
+SELECT new_emp().name;
+ERROR: parser: parse error at or near "."
</screen>
</para>

- This example makes use of the
- function notation for projecting attributes. The simple way
- to explain this is that we can usually use the
+ Another approach is to use
+ functional notation for extracting attributes. The simple way
+ to explain this is that we can use the
notations <literal>attribute(table)</> and <literal>table.attribute</>
interchangeably:
+<programlisting>
+SELECT name(new_emp());

+ name

- The reason why, in general, we must use the function
- syntax for projecting attributes of function return
- values is that the parser just doesn't understand
- the dot syntax for projection when combined
- with function calls.

Another way to use a function returning a row result is to declare a
second function accepting a row type parameter, and pass the function
