+<H4><A NAME="4.24">4.24</A>) How do I do an <i>outer</i> join?<BR></H4><P>
+PostgreSQL does not support outer joins in the current release. They can
+be simulated using <small>UNION</small> and <small>NOT IN</small>. For
+example, when joining <i>tab1</i> and <i>tab2,</i> the following query
+does an <i>outer</i> join of the two tables:
+<PRE>
+ SELECT tab1.col1, tab2.col2
+ FROM tab1, tab2
+ WHERE tab1.col1 = tab2.col1
+ UNION ALL
+ SELECT tab1.col1, NULL
+ FROM tab1
+ WHERE tab1.col1 NOT IN (SELECT tab2.col1 FROM tab2)
+ ORDER BY tab1.col1
+</PRE>
