compatibility for release 7.2 and earlier.  I have not altered any
mentions of release 7.3 or later.  The release notes were not modified,
so the changes are still documented, just not in the main docs.

In releases of <productname>PostgreSQL</productname> prior to 7.1, the
default behavior was not to include child tables in queries. This was
found to be error prone and is also in violation of the SQL
standard. Under the old syntax, to include the child tables you append
<literal>*</literal> to the table name. For example:
<programlisting>
SELECT * from cities*;
</programlisting>
You can still explicitly specify scanning child tables by
appending <literal>*</literal>, as well as explicitly specify not
scanning child tables by writing <literal>ONLY</literal>. But
beginning in version 7.1, the default behavior for an undecorated
table name is to scan its child tables too, whereas before the
default was not to do so. To get the old default behavior,
disable the <xref linkend="guc-sql-inheritance"> configuration
found to be error prone and also in violation of the SQL
standard. You can get the pre-7.1 behavior by turning off the
<xref linkend="guc-sql-inheritance"> configuration
option.
