OK, pg_upgrade has code to report invalid gin and hash indexes because of changes between PG 8.3 and 8.4. Is this something we would do for 9.0 to 9.1? You are saying it would have to be run before the upgrade. Can it not be run after? I can output a script to VACUUM all such indexes, and tell users to manually REINDEX any index that generates a warning messasge. I don't have any way to automate an optional REINDEX step. -- Bruce Momjian <br...@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. + -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
