postfix-policyd installation omits a table when creating the database

When reviewing the logs on a mail server, I discovered that messages that had passed the various anti-spam tests all had the message "blacklist_dnsname=bypass" flagged against them.
e.g.
Jul 28 12:55:29 server-name postfix-policyd: rcpt=7493, blacklist_dnsname=bypass, host=XXX.XXX.XXX.XXX (aluminium-oneisi.ccmdcampaigns.net), <email address hidden>, <email address hidden>, size=0

This indicates that the blacklist_dnsname module experienced an error when trying to interrogate the database. Examining the structure of the database revealed that the blacklist_dnsname table was missing.

The database creation script needs to include the following SQL to create the database correctly:

-- start SQL
CREATE TABLE `blacklist_dnsname` (
  `_blacklist` char(60) NOT NULL default '',
  `_description` char(60) NOT NULL default '',
  `_expire` int(10) unsigned NOT NULL default '0',
  UNIQUE KEY `_blacklist` (`_blacklist`),
  KEY `_expire` (`_expire`)
) ENGINE=MyISAM;
-- end SQL
