The view pg_stat_statements gains two columns: - parallel_workers_to_launch, the number of parallel workers planned to be launched. - parallel_workers_launched, the number of parallel workers actually launched. The ratio of both columns offers hints that parallel workers are lacking on a per-statement basis, requiring some tuning, in coordination with "calls", the number of times a query is executed. As of now, these numbers are tracked within Gather and GatherMerge nodes. They could be extended to utilities that make use of parallel workers (parallel btree and brin, VACUUM). The module is bumped to 1.12. Author: Guillaume Lelarge Discussion: https://postgr.es/m/CAECtzeWtTGOK0UgKXdDGpfTVSa5bd_VbUt6K6xn8P7X+_dZqKw@mail.gmail.com
