Columns 30

As listed in the PostgreSQL 18 manual.

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.)
