You could probably write a function in postgres (say, "matchcount()") 
which returns the match count (possibly using perl and a regex).

SELECT matchcount(message,'sql') AS matchcount, id
FROM tablename
WHERE message LIKE '%sql%'
ORDER BY matchcount(message,'sql') DESC

The ORDER BY will probably fail, but you can try :)
