Thanks Andres. Both higher than average I guess, although it depends on what is considered 'a lot' and 'a long time'. The startup process was running for a few months. There are ~500k entries in pg_class, of which most are (Timescale) partitions. However, even with this number of items in pg_class I would't expect wraparound to happen frequently? These are not dropped/recreated. I've monitored "select count(*) from pg_class" for a while to see if it changes often, and while there are changes during the day (likely temporary tables being created), it also doesn't nearly happen at a frequency that will get us to a wraparound quickly.

Oids aren't just consumed by pg_class though. And I do see system oid growing quickly (when doing CREATE TABLE twice with a minute in between, then checking the oid difference of the table). I don't know how to investigate the cause of this. What would be the best way to check what could be consuming these oids so quickly?
