Обсуждение: pgsql: Cleanup initialization of Hot Standby.
Log Message: ----------- Cleanup initialization of Hot Standby. Clarify working with reanalysis of requirements and documentation on LogStandbySnapshot(). Fixes two minor bugs reported by Tom Lane that would lead to an incorrect snapshot after transaction wraparound. Also fix two other problems discovered that would give incorrect snapshots in certain cases. ProcArrayApplyRecoveryInfo() substantially rewritten. Some minor refactoring of xact_redo_apply() and ExpireTreeKnownAssignedTransactionIds().
