<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>.
