PostgreSQL 18 introduces pg_restore_relation_stats() and pg_restore_attribute_stats() functions that enable developers to copy production database statistics to development environments, allowing accurate query plan simulation without needing full production data.
Background
Database query planners rely on statistics to optimize execution plans, but statistics often differ between production and development environments, leading to inconsistent query performance.
