Hi, One of the questions I have about parallel query is whether it should be enabled by default. That is, should we make the default value of max_parallel_degree to a value higher than 0? Perhaps 1, say?
There are some good reasons why this might be a bad idea, such as: - As discussed on a nearby thread, there is every possibility of nasty bugs. - Parallel query uses substantially more resources than a regular query, which might overload your system. On the other hand: - Features that are on by default get more testing and thus might get less buggy more quickly. - A lot of people don't change the default configuration and thus wouldn't get any benefit from the feature if it's not on by default.
