Just to mention one issue we had here:
In 8.1 we did this to retrieve all data from a specific date:
SELECT * FROM xxx
WHERE <timestamp_column> LIKE '2008-05-20%'
In 8.3 we had to change to:
SELECT * FROM xxx
WHERE <timestamp_column> >= CAST('2008-05-20' as timestamp) AND
<timestamp_column> < CAST('2008-05-21' as timestamp)
