At your stated rate of 1.5 million OIDs per day it will take just under eight years before you wraparound. That's a lot of OIDs and most databases don't get anywhere near that many, which is why it's not a big deal for most people... > Also, do you know what is actually using the OIDs - transactions? Inserting new rows into a table somewhere that has OIDs. Just using transactions won't do it. Note, some system catalogs use oids, so some DDL statements can do it. This gives you a list of tables that use OIDs. Maybe it can help you track down the problem. select attrelid::regclass from pg_attribute inner join pg_class on (attrelid = oid) where attname = 'oid' and relkind = 'r'; Have a nice day, -- Martijn van Oosterhout <kleptog@xxxxxxxxx> http://svana.org/kleptog/ > From each according to his ability.
