The catalog <code class="structname">pg_seclabel</code> stores security
labels on database objects. Security labels can be manipulated
with the <a class="xref" href="sql-security-label.html" title="SECURITY LABEL"><span class="refentrytitle">SECURITY LABEL</span></a> command. For an easier
way to view security labels, see <a class="xref" href="view-pg-seclabels.html" title="51.83. pg_seclabels">Section 51.83</a>.
</p><p>
See also <a class="link" href="catalog-pg-shseclabel.html" title="51.48. pg_shseclabel"><code class="structname">pg_shseclabel</code></a>,
which performs a similar function for security labels of database objects
that are shared across a database cluster.
