These tables are owned by postgres not the db owner user, other than that they seem to be a replica from a specific time in the past. I suspect that a failed backup might have cased these, but I am not sure. I couldn't find any info tables ending in _copy and also I thought that backups run in a transaction so even if they create temporary tables, they should disappear even when the backups fail.

It sounds like something that a client app would do, possibly as part of a (failed) data migration. What app is using the database?
