Waiting for PostgreSQL 19 – Support COPY TO for partitioned tables.
Read OriginalThe article details a new feature in PostgreSQL 19 that allows the COPY TO command to work directly on partitioned tables. Previously, users had to use a slower COPY (SELECT ...) TO workaround. The commit improves performance by avoiding query processing overhead and applies row-level security policies correctly. The author includes performance test results and explains the practical benefits for database management.
