In July 2025, during the PG19-1 CommitFest, I reviewed a patch targeting the lack of parallelism when adding foreign keys in pg_restore. Around the same time, I was helping a client with a large production migration where pg_restore dragged on for more than 24 hours and crashed multiple times. In this blog, I will talk about the technical limitations in PostgreSQL, the proposed fix, and a practical workaround for surviving large restores.
