Report "All Tickets By Milestone" does not work with PostgreSQL

[anonymous]

When I want to view 6th report (All Tickets By Milestone) Trac reports error:

Report execution failed: 
ERROR: column "modified" does not exist 
SELECT p.value AS __color__, t.milestone AS __group__, (CASE status WHEN 'closed' THEN 'color: #777; background: #ddd; border-color: #ccc;' ELSE (CASE owner WHEN 'mn' THEN 'font-weight: bold' END) END) AS __style__, id AS ticket, summary, component, status, resolution,version, t.type AS type, priority, owner, changetime AS modified, time AS _time,reporter AS _reporter FROM ticket t,enum p WHERE p.name=t.priority AND p.type='priority' ORDER BY (milestone IS NULL), milestone DESC, (status = 'closed'), (CASE status WHEN 'closed' THEN modified ELSE (-1)*p.value END) DESC

I have corrected it with change in database:

update report set sql='SELECT p.value AS __color__,
   t.milestone AS __group__,
   (CASE status 
      WHEN ''closed'' THEN ''color: #777; background: #ddd; border-color: #ccc;''
      ELSE 
        (CASE owner WHEN ''$USER'' THEN ''font-weight: bold'' END)
    END) AS __style__,
   id AS ticket, summary, component, status, 
   resolution,version, t.type AS type, priority, owner,
   changetime AS modified,
   time AS _time,reporter AS _reporter
  FROM ticket t,enum p
  WHERE p.name=t.priority AND p.type=''priority''
  ORDER BY (milestone IS NULL), milestone DESC, (status = ''closed''), 
        (CASE status WHEN ''closed'' THEN changetime ELSE (-1)*p.value::int END) DESC
' where id=6;

I have changed:

1. in ORDER BY I renamed modified to changetime (PostgreSQL doesn't use aliases in ORDER BY)
2. cast p.value to int
