Hi Vincent and Ludovic, I'm sorry, I didn't see the answer. I saw this line in the logs and (now I remember...) wanted to ask, whether it is possible to delete the rows from xwikilongs without serious problems in later progress. Which other tables could be "cleaned"? Are there even more data sets which could be called temporary? The upgrade would be a good idea for cleaning up. After my last post on this thread I didn't test further options to upgrade, because I didn't have time to do it. So there are now new results from my side. BTW: Dandre, who had a problem with upgrading while using Postgres, wrote me a mail and asked if I had any suggestions for his problem. We will now try to solve the problem together and report results to the mailing list. This week I'm not in office, but I hope next week I will have time to test to upgrade (to b3). After problems during upgrade with 1.0b1 we decided to wait for upgrading our wiki (0.9.840 - runs very good (with Postgres 8.1 :-)), but sometimes there are unreproceable errors with file upload) until 1.0 final is released. Best regards, Fabian.
