ANALYZE on a table with inheritance children analyzes all the child tables in a loop. When stepping to next child table, it updated the child rel ID value in the command progress stats, but did not reset the 'sample_blks_total' and 'sample_blks_scanned' counters. acquire_sample_rows() updates 'sample_blks_total' as soon as the scan starts and 'sample_blks_scanned' after processing the first block, but until then, pg_stat_progress_analyze would display a bogus combination of the new child table relid with old counter values from the previously processed child table. Fix by resetting 'sample_blks_total' and 'sample_blks_scanned' to zero at the same time that 'current_child_table_relid' is updated. Backpatch to v13, where pg_stat_progress_analyze view was introduced. Reported-by: Justin Pryzby Discussion: https://www.postgresql.org/message-id/20230122162345.GP13860%40telsasoft.com |
