<para>
Although it is not strictly a function and does not appear in \df
in psql, <command>ARRAY()</command>, mentioned in <xref
linkend="sql-syntax-array-constructors"> acts much like a
<literal>table function</literal> (equivalently, a
<literal>set-returning function</literal> or a
<acronym>SRF</acronym>--see <xref linkend="queries-tablefunctions">)
which takes <type>anyarray</type> and returns a set of
<type>anyelement</type>.
