The DBAppender in 1.3 has a logging_event table. It appears that two of the columns (sequence_number and reference_flag) come from info that is available in 1.3 but not 1.2.8. Is that correct?
I made my own DBAppender and I thought that it would be good for me to use the same schema so when we move to 1.3 I can just switch to the DBAppender in log4j. Right now I am putting -1 in those columns because it doesn't appear that I can access the source of that data in 1.2.8. James Stauffer
