<function>to_timestamp</function> and <function>to_date</function>
skip multiple blank space in converted string if the <literal>FX</literal> option
is not used. <literal>FX</literal> must be specified as the first item
in the template; for example
<literal>to_timestamp('2000 JUN','YYYY MON')</literal> is right, but
<literal>to_timestamp('2000 JUN','FXYYYY MON')</literal> returns error,
because to_timestamp() expects one blank space only.
skip blank space if the <literal>FX</literal> option is
not used. <literal>FX</literal> must be specified as the first item
