The full dump and restore is not very attractive due to the downtime involved. pg_migrator is an attractive option, but we have butted up again the integer datetime timestamp problem: "Old and new pg_controldata date/time storage types do not match. You will need to rebuild the new server with configure --disable-integer-datetimes or get server binaries built with those options." We also noticed that the are non id rpms available for 8.3, but we couldn't find any for 8.4 here: https://projects.commandprompt.com/public/pgcore So, is the best option to compile postgres from source? Is there anyway to change the storage of timestamps in our 8.3 db online (I am guessing no...)? Mostly I just need a sanity check before I waste a bunch of time :)
