noise words for the last twelve years, for compatibility with Berkeley-era
output formatting of the special INVALID values for those datatypes.
Considering that the datatypes themselves have been deprecated for awhile,
this is taking backwards compatibility a little far.  Per gripe from Josh
Berkus.

<para>
The key word <literal>ABSTIME</literal> is ignored for historical
reasons: In very old releases of
<productname>PostgreSQL</productname>, invalid values of type <type>abstime</type>
were emitted as <literal>Invalid Abstime</literal>. This is no
longer the case however and this key word will likely be dropped in
a future release.
