Hi, I noticed the patch no longer applies on the latest source. And few comments. 1) +static void set_parallel_vacuum_index_status(ParallelVacuumState *pvs, + bool bulkdel, + int num_index_scans); +static void parallel_vacuum_all_indexes(ParallelVacuumState *pvs, bool bulkdel, + int num_index_scans); ... +static bool index_can_participate_parallel_vacuum(Relation indrel, + int num_index_scans); Maybe the parameter num_index_scans can be replaced by a bool flag since it is only used in the check "num_index_scans > 0" and "num_index_scans == 0". 2) + /* Reinitialize the parallel context to relaunch parallel workers */ + if (!pvs->first_time) It seems the ParallelVacuumState::first_time was not initialized before ? Best regards Hou zj
