Alexander Korotkov 47f99a407d reindexdb: Add the index-level REINDEX with multiple jobs ... Straight-forward index-level REINDEX is not supported with multiple jobs as we cannot control the concurrent processing of multiple indexes depending on the same relation. Instead, we dedicate the whole table to certain reindex job. Thus, if indexes in the lists belong to different tables, that gives us a fair level of parallelism. This commit teaches get_parallel_object_list() to fetch table names for indexes in the case of index-level REINDEX. The same tables are grouped together in the output order, and the list of indexes is also rebuilt to match that order. Later during processingof that list, we push indexes belonging to the same table into the same job.
