[Zope] ZSQL Errors

[Joel Burton]

<dtml-try>
  <dtml-in select>
    <dtml-var show>
  </dtml-in>
<dtml-except>
  <dtml-var error_value>
</dtml-try>

If there's an SQL error raised by PostgreSQL, you'll get the error message
in error_value.
If you don't use the try/except wrap, Zope will raise an error which shows
the PG error.

Zope 2.5.0; PG 7.3cvs (but should be the same w/earlier versions of PG). I'm
using zpysopg; this might be quite different with other PG adapters.
