Parallel Vector Index Rebuild in Postgres

Semab Tariq takes a look at parallel index building in pgvector:

Parallel Index Build refers to the capability to build indexes using parallel processing. In simpler terms, it means that multiple workers or threads can be utilized simultaneously to create an index, which can significantly speed up the index creation process.

When performing an index build operation, PostgreSQL can divide the work among multiple parallel workers, each responsible for building a portion of the index.
