As I recall (I could be wrong) Slony syncs the whole set as a single transaction. So if he has his entire database as a set he may have a problem regardless of the largest or smallest table. I would also agree that 30 million rows is likely not a problem but he should still check his velocity. Sincerely, Joshua D.
