Previously the descriptions of tup_returned and tup_fetched columns in pg_stat_database view were confusing. This commit improves them so that they represent the following formulas of those columns more accurately. * pg_stat_database.tup_returned = sum(pg_stat_all_tables.seq_tup_read) + sum(pg_stat_all_indexes.idx_tup_read) * pg_stat_database.tup_fetched = sum(pg_stat_all_tables.idx_tup_fetch) In these formulas, note that the counters for some system catalogs like pg_database shared across all databases of a cluster are excluded from the calculations of sum.
