Well, as a crosscheck, could you list your requirements? Do you need anything more than outputting data in a format compatible to whats stored in sl_log_*? You wouldn't have sl_actionseq, everything else should be there (Well, you would need to do lookups to get the tableid, but thats not really much of a problem). The results would be ordered in complete transactions, in commit order. I guess the other tables would stay as they are as they contain the "added value" of slony?
