<para>The most typical usage is the composing of get-keyword style vector, for ex:
</para>
<programlisting><![CDATA[
SELECT DB.DBA.VECTOR_CONCAT_AGG (vector (U_NAME, U_ID))
FROM DB.DBA.SYS_USERS
ORDER BY U_NAME;
]]></programlisting>
<para>which returns a vector of passed values. The order of items in the vector repeats the order of passing
argument vectors to the aggregate.
</para>
<programlisting><![CDATA[
(dba, 0, dav, 2, administrators, 3, nobody, 5, nogroup, 6, __rdf_repl, 7, SPARQL_SELECT, 100, SPARQL_SPONGE, 101, ... )
