Don't qualify type pg_catalog.text in extend-extensions-example.

nmisch · nmisch · commit 2c8974e6a02d · 2018-03-23T20:31:06.000-07:00
Extension scripts begin execution with pg_catalog at the front of the
search path, so type names reliably refer to pg_catalog.  Remove these
superfluous qualifications.  Earlier &lt;programlisting&gt; of this &lt;sect1&gt;
already omitted them.  Back-patch to 9.3 (all supported versions).
