Thank you very much, Robert. I propose it be appended to the 8.4
comprehensive manual, Chapter 53.2 TOAST. (And the 9 manual, if it's
true for 9. I haven't touched 9 yet but I'm assuming this hasn't
changed?)

Here is the patch for 9.0.2 DocBook SGML:

*** storage.sgml.orig 2011-01-08 10:38:23.000000000 -0500
--- storage.sgml 2011-01-08 10:48:53.000000000 -0500
***************
*** 404,409 ****
--- 404,421 ----
comparison table, in which all the HTML pages were cut down to 7 kB to fit.
</para>

+ <para>

+ reltoastrelid='pg_toast_12513885'::regclass;
+ </programlisting>
+ </para>
+
</sect1>

And here is the patch for the 8.4.6 documentation:

*** storage.sgml.orig 2011-01-08 10:56:04.000000000 -0500
--- storage.sgml 2011-01-08 10:56:06.000000000 -0500
