I assume 8.3 vacuumdb did not generate these errors. If it was 8.4 I would suggest it was because we don't copy visibility map files from pre-9.1 because those were not crash-safe, but 8.3 didn't have visibility map files (added in PG 8.4), so 8.3 should have been checking the exact same transaction ids as 9.1. Basically, I can't think of a cause. -- Bruce Momjian <bruce@xxxxxxxxxx> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. + -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
