This actually depends on how the PITR mechanism is implemented. A
common approach is to do filesystem backup followed by log shipping
to multiple, redundant destinations. In this scenario, you only lose
what isn't in the logs, which in the case of Postgres means you only
lose uncommitted transactions.
