We have some very large Heroku Postgres tables that we only append to, only extremely rarely modifying old rows. We can't sync these using XMIN because the wraparound fixes don't work for Heroku Postgres, but they're really not well suited to Teleport sync due to their size (it already takes about 10 hrs for the connector to sync).

We really need either a fix for the XMIN wraparound issue or a new kind of sync in order to be able to keep syncing these tables in the long term.
