As per my understanding, 'pg_statio_all_indexes' displays "idx_blks_hit" using "pg_stat_get_blocks_hit(oid)" where the function "pg_stat_get_blocks_hit" gets number of disk block requests found in cache for a table or index.
Hi, I'm not sure about the value idx_blks_hit of pg_statio_all_indexes view. Is it total value of touched pages, or do I get total value when I add idx_blks_read to it? In other words - does idx_blks_hit cover also physical reads?
Thanks, David Hoksza
