postinst file fails if /var/lib/placement/placement.sqlite exists

[Gordon Atwood]

postinst file contains these instructions:

<snip>
if [ -e /var/lib/placement/placement.sqlite ];
    then
        chmod placement:placement /var/lib/placement/placement.sqlite
        chmod 640 /var/lib/placement/placement.sqlite
    fi
<snip>

The first 'chmod' has invalid syntax.

I suspect it should read:
  chown -R placement:placement /var/lib/placement/placement.sqlite
