Each file was taking about 30 seconds to be processed. About 4 seconds to create the `users` table and have the CSV data loaded into it and anything between 20 and 30 seconds to insert the data from `users` into `users_no_dups`. Do you see anything suspicious in the logs, i.e. something in the realms of running out of transaction IDs? I set the log to debug1. I haven't seen anything that called my attention, but I am not really sure what to look for, so perhaps I missed it. Any suggestions on what to look for or any specific log configuration to do? Not necessarily, if you'd run out of tx IDs you would notice that cleary, I guess. I also think that this is not the issue. [...] Recreating the table now isn't really providing any improvements. I tried recreating it with a `fillfactor` of `10`, but it was taking too long and too much space (the table had 300GB with the fillfactor set to 30; with it set to 10 it went up to almost 1TB). To me it sounds like the UK/PK is getting too much to write. A possible solution could be to start partitioning the table. I thought about partitioning it, but I can't figure out on what. The `user_id` column is a number that is somewhat random so I don't know what kinds of range I would use for it. I will try to look at the values again and see if there is something that I could perhaps use as a range. Any other suggestions? Depending on granularity, maybe partition on `created_ts`?
