<para>

<function>to_timestamp</function> and <function>to_date</function>

skip blank space if the <literal>FX</literal> option is

not used. <literal>FX</literal> must be specified as the first item

in the template.

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.
