Large tables proxy_package_download and organization_package_download

[martinvonwittich]

In our repman instance, there are two large tables proxy_package_download and organization_package_download, which consume a lot of disk space and increase the size of our daily database dumps:

repman=# SELECT nspname || '.' || relname AS "relation",
    pg_size_pretty(pg_relation_size(C.oid)) AS "size"
  FROM pg_class C
  LEFT JOIN pg_namespace N ON (N.oid = C.relnamespace)
  WHERE nspname NOT IN ('pg_catalog', 'information_schema')
  ORDER BY pg_relation_size(C.oid) DESC
  LIMIT 5;
                 relation                  |  size

 public.proxy_package_download             | 1999 MB
 public.organization_package_download      | 475 MB
 public.organization_package_download_pkey | 83 MB
 public.proxy_package_idx                  | 82 MB
 public.proxy_download_date_idx            | 80 MB

Apparently these tables are effectively log files for package downloads?

repman=# select package, date, version, user_agent from proxy_package_download order by date desc limit 10 ;
           package           |        date         |  version   |                                      user_agent

Assuming that these aren't necessary for operation, is there a way to disable this logging, or a way to delete old entries from these tables? Would it be safe to manually delete old records directly in the database, e.g. with delete from from proxy_package_download where date < now() - '1 year'::interval?
