<para>
<function>pg_result_error</function> returns any error message
associated with the <parameter>result</parameter> resource. Therefore,
the user has a better chance of getting the correct error message than
with <function>pg_last_error</function>.
</para>
<para>
The function <function>pg_result_error_field</function> can give much greater
detail on result errors than <function>pg_result_error</function>.
</para>
<para>
Because <function>pg_query</function> returns &false; if the query fails,
you must use <function>pg_send_query</function> and
<function>pg_get_result</function> to get the result handle.
