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
