postgres-backup-and-operational-readiness

Use when designing, reviewing, or hardening PostgreSQL backup, point-in-time recovery, and day-2 operational readiness against stated RPO/RTO targets. Produces backup strategy (pg_basebackup or pgBackRest with WAL archiving for PITR), rehearsed restore drills with measured RPO/RTO, retention and cost posture, observability for replication lag, storage health, bloat, transaction-ID wraparound, and connection saturation, plus runbook inputs for failover, vacuum-freeze emergencies, and connection exhaustion. Do not use for replication topology design, schema or migration work, query optimization, or access-control hardening; use postgres-replication-and-ha-readiness, postgres-schema-and-migration, postgres-indexing-and-query-optimization, or postgres-security-and-data-access-hardening instead.
