Does anyone know if parallel query execution just happens by default or do you have to tell PG that you want it?

- jeltz 10y agoYou have to enable it by configuring the maximum number of workers per query, and then the query planner tries to figure out if the query would benefit from a parallel execution. This is the first release with parallelism so I would not be surprised if the query planner gets this wrong in some cases.
