Columns 30
| Column | Type | Description / reference |
|---|---|---|
relid | oid | OID of a table |
schemaname | name | Name of the schema that this table is in |
relname | name | Name of this table |
seq_scan | bigint | Number of sequential scans initiated on this table |
last_seq_scan | timestamp with time zone | The time of the last sequential scan on this table, based on the most recent transaction stop time |
seq_tup_read | bigint | Number of live rows fetched by sequential scans |
idx_scan | bigint | Number of index scans initiated on this table |
last_idx_scan | timestamp with time zone | The time of the last index scan on this table, based on the most recent transaction stop time |
idx_tup_fetch | bigint | Number of live rows fetched by index scans |
n_tup_ins | bigint | Total number of rows inserted |
n_tup_upd | bigint | Total number of rows updated. (This includes row updates counted in n_tup_hot_upd and n_tup_newpage_upd, and remaining non-HOT updates.) |
n_tup_del | bigint | Total number of rows deleted |
n_tup_hot_upd | bigint | Number of rows HOT updated. These are updates where no successor versions are required in indexes. |
n_tup_newpage_upd | bigint | Number of rows updated where the successor version goes onto a new heap page, leaving behind an original version with a t_ctid field that points to a different heap page. These are always non-HOT updates. |
n_live_tup | bigint | Estimated number of live rows |
n_dead_tup | bigint | Estimated number of dead rows |
n_mod_since_analyze | bigint | Estimated number of rows modified since this table was last analyzed |
n_ins_since_vacuum | bigint | Estimated number of rows inserted since this table was last vacuumed (not counting VACUUM FULL) |
last_vacuum | timestamp with time zone | Last time at which this table was manually vacuumed (not counting VACUUM FULL) |
last_autovacuum | timestamp with time zone | Last time at which this table was vacuumed by the autovacuum daemon |
last_analyze | timestamp with time zone | Last time at which this table was manually analyzed |
last_autoanalyze | timestamp with time zone | Last time at which this table was analyzed by the autovacuum daemon |
vacuum_count | bigint | Number of times this table has been manually vacuumed (not counting VACUUM FULL) |
autovacuum_count | bigint | Number of times this table has been vacuumed by the autovacuum daemon |
analyze_count | bigint | Number of times this table has been manually analyzed |
autoanalyze_count | bigint | Number of times this table has been analyzed by the autovacuum daemon |
total_vacuum_time | double precision | Total time this table has been manually vacuumed, in milliseconds (not counting VACUUM FULL). (This includes the time spent sleeping due to cost-based delays.) |
total_autovacuum_time | double precision | Total time this table has been vacuumed by the autovacuum daemon, in milliseconds. (This includes the time spent sleeping due to cost-based delays.) |
total_analyze_time | double precision | Total time this table has been manually analyzed, in milliseconds. (This includes the time spent sleeping due to cost-based delays.) |
total_autoanalyze_time | double precision | Total time this table has been analyzed by the autovacuum daemon, in milliseconds. (This includes the time spent sleeping due to cost-based delays.) |
