If not, maybe you could arrange to send me a dump off-list. A short test-case script would be better, but let's not waste huge amounts of person-time to save a few hours of downloading ... That's what I was planning to do. I'll generate a table with dummy entries. I think we may try to use the smaller base table first. Once I can reproduce the problem I'll dump the database into a file and send it to you. Is there a server that I can upload the data to?
