## Summary
PostgreSQL 19 has reached its first release candidate stage. The upcoming major release focuses on practical improvements in three areas: database maintenance operations, query planner behavior, and replication reliability. Database administrators and application developers should begin testing against this RC.

## What to test in PostgreSQL 19 RC1
- Database maintenance operations have received practical advances
- Query planner behavior includes improvements worth validating against existing workloads
- Replication changes may affect failover and standby configurations
- First RC status means feature freeze is in effect; remaining changes are bug fixes only

## Why it matters
As a major PostgreSQL release approaching general availability, these changes will affect managed service providers, self-hosted deployments, and applications dependent on specific planner or replication behaviors. Early RC testing allows teams to identify regressions before the final release.
