This was always intended to work, but due to an oversight in max_parallel_hazard_walker, it didn't. In testing, we missed the fact that it was only working for custom plans, where the parameter value has been substituted for the parameter itself early enough that everything worked. In a generic plan, the Param node survives and must be treated as parallel-safe. SerializeParamList provides for the transmission of parameter values to workers. Amit Kapila with help from Kuntal Ghosh. Some changes by me. Discussion: http://postgr.es/m/CAA4eK1+_BuZrmVCeua5Eqnm4Co9DAXdM5HPAOE2J19ePbR912Q@mail.gmail.com
