The unwrapping behavior of lax mode can lead to surprising results. For
instance, the following query using the <literal>.**</literal> accessor
selects every <literal>HR</literal> value twice:
<screen>
<prompt>=&gt;</prompt> <userinput>select jsonb_path_query(:'json', 'lax $.**.HR');</userinput>

This happens because the <literal>.**</literal> accessor selects both
the <literal>segments</literal> array and each of its elements, while
the <literal>.HR</literal> accessor automatically unwraps arrays when
using lax mode. To avoid surprising results, we recommend using
the <literal>.**</literal> accessor only in strict mode. The
following query selects each <literal>HR</literal> value just once:
<screen>
<prompt>=&gt;</prompt> <userinput>select jsonb_path_query(:'json', 'strict $.**.HR');</userinput>
