In the context of PostgreSQL's Point-in-Time Recovery (PITR) as discussed in "The Complete PostgreSQL Point-in-Time Recovery (PITR) Course 2026: From Zero to Expert!", what is the primary role of WAL (Write-Ahead Logging) archives in enabling recovery to a specific transaction?
When performing a Point-in-Time Recovery (PITR) using PostgreSQL, which of the following is the MOST critical pre-requisite for ensuring successful recovery to a specific transaction ID (XID) or timestamp?
Consider a scenario where a PostgreSQL database experienced corruption at 10:00 AM. You have a base backup taken at 8:00 AM and WAL archives available from 8:00 AM onwards. You want to recover to the latest consistent state *before* the corruption occurred. If the last valid transaction before corruption committed at 9:55 AM, what would be the target recovery point if using `recovery_target_time` in `postgresql.conf` or `recovery.signal`?
