<para>
The <filename>dummy_seclabel</> module exists only to support regression
testing of the <command>SECURITY LABEL</> statement. It is not intended
to be used in production.
</para>
<sect2>
<title>Rationale</title>
<para>
The <command>SECURITY LABEL</> statement allows the user to assign security
labels to database objects; however, security labels can only be assigned
when specifically allowed by a loadable module, so this module is provided
to allow proper regression testing.
</para>
<para>
Security label providers intended to be used in production will typically be
dependent on a platform-specific feature such as
<productname>SE-Linux</productname>. This module is platform-independent,
and therefore better-suited to regression testing.
</para>
</sect2>
<sect2>
<title>Usage</title>
<para>
Here's a simple example of usage:
</para>
<programlisting>
# postgresql.conf
shared_preload_libraries = 'dummy_label'
</programlisting>
<programlisting>
postgres=# CREATE TABLE t (a int, b text);
CREATE TABLE
postgres=# SECURITY LABEL ON TABLE t IS 'classified';
SECURITY LABEL
</programlisting>
<para>
The <filename>dummy_seclabel</> provides only four hardcoded
labels: <literal>unclassified</>, <literal>classified</>,
<literal>secret</>, <literal>top secret</> and <literal>trusted</>.
It does not allow any other strings as security labels.
</para>
<para>
These labels are not used to enforce access controls. They are only used
to check whether the <command>SECURITY LABEL</> statement works as expected,
or not.
