In a bitmap scan the output of several indexes can be combined via AND or OR rules, so it is difficult to associate individual heap row fetches with specific indexes when a bitmap scan is used. Therefore, a bitmap scan increments the pg_stat_all_indexes.idx_tup_read count(s) for the index(es) it uses, and it increments the pg_stat_all_tables.idx_tup_fetch count for the table, but it does not affect pg_stat_all_indexes.idx_tup_fetch. The optimizer also accesses indexes to check for supplied constants whose values are outside the recorded range of the optimizer statistics because the optimizer statistics might be stale.","columns":[{"name":"relid","type":"oid","description":"OID of the table for this index","hidden":false,"type_oid":26,"attnum":1,"type_modifier":-1,"array_dimensions":0,"not_null":false},{"name":"indexrelid","type":"oid","description":"OID of this index","hidden":false,"type_oid":26,"attnum":2,"type_modifier":-1,"array_dimensions":0,"not_null":false},{"name":"schemaname","type":"name","description":"Name of the schema this index is in","hidden":false,"type_oid":19,"attnum":3,"type_modifier":-1,"array_dimensions":0,"not_null":false},{"name":"relname","type":"name","description":"Name of the table for this index","hidden":false,"type_oid":19,"attnum":4,"type_modifier":-1,"array_dimensions":0,"not_null":false},{"name":"indexrelname","type":"name","description":"Name of this index","hidden":false,"type_oid":19,"attnum":5,"type_modifier":-1,"array_dimensions":0,"not_null":false},{"name":"idx_scan","type":"bigint","description":"Number of index scans initiated on this index","hidden":false,"type_oid":20,"attnum":6,"type_modifier":-1,"array_dimensions":0,"not_null":false},{"name":"last_idx_scan","type":"timestamp with time zone","description":"The time of the last scan on this index, based on the most recent transaction stop time","hidden":false,"type_oid":1184,"attnum":7,"type_modifier":-1,"array_dimensions":0,"not_null":false},{"name":"idx_tup_read","type":"bigint","description":"Number of index entries returned by scans on this index","hidden":false,"type_oid":20,"attnum":8,"type_modifier":-1,"array_dimensions":0,"not_null":false},{"name":"idx_tup_fetch","type":"bigint","description":"Number of live table rows fetched by simple index scans using this index","hidden":false,"type_oid":20,"attnum":9,"type_modifier":-1,"array_dimensions":0,"not_null":false},{"name":"stats_reset","type":"timestamp with time zone","description":"Time at which these statistics were last reset","hidden":false,"type_oid":1184,"attnum":10,"type_modifier":-1,"array_dimensions":0,"not_null":false}],"source_url":"https://www.postgresql.org/docs/19/monitoring-stats.html#PG-STAT-ALL-INDEXES-VIEW","source_path":"sources/postgresql/19/monitoring-stats.html","schema_source":"runtime+documentation","definition_source_url":"https://raw.githubusercontent.com/postgres/postgres/REL_19_BETA3/src/backend/catalog/system_views.sql","definition_source_path":"sources/postgresql/19/source/system_views.sql","source_column_count":10,"documentary_schema_source":"documentation","relation_oid":12201,"shared":false,"relkind":"v","system_columns":[],"runtime_validation":{"release":"19beta3","source_tag":"REL_19_BETA3","source_path":"sources/runtime/19.json","sha256":"2d1f0c65a5fa656dc86cb9648f80baee3654b976dc6ba69190cd1d49c61e6d9a","download":"/data/runtime/19.json","passed":true}},{"name":"pg_stat_all_tables","kind":"statistics","summary":"One row for each table in the current database, showing statistics about accesses to that specific table.

statistics","description":"The catalog pg_statistic stores statistical data about the contents of the database. Entries are created by ANALYZE and subsequently used by the query planner. Note that all the statistical data is inherently approximate, even assuming that it is up-to-date.\n\nNormally there is one entry, with stainherit = false, for each table column that has been analyzed. If the table has inheritance children or partitions, a second entry with stainherit = true is also created. This row represents the column's statistics over the inheritance tree, i.e., statistics for the data you'd see with SELECT column FROM table*, whereas the stainherit = false row represents the results of SELECT column FROM ONLY table.\n\npg_statistic also stores statistical data about the values of index expressions. These are described as if they were actual data columns; in particular, starelid references the index. No entry is made for an ordinary non-expression index column, however, since it would be redundant with the entry for the underlying table column. Currently, entries for index expressions always have stainherit = false.\n\nSince different kinds of statistics might be appropriate for different kinds of data, pg_statistic is designed not to assume very much about what sort of statistics it stores. Only extremely general statistics (such as nullness) are given dedicated columns in pg_statistic. Everything else is stored in “slots”, which are groups of associated columns whose content is identified by a code number in one of the slot's columns. For more information see src/include/catalog/pg_statistic.h.\n\npg_statistic should not be readable by the public, since even statistical information about a table's contents might be considered sensitive. (Example: minimum and maximum values of a salary column might be quite interesting.) pg_stats is a publicly readable view on pg_statistic that only exposes information about those tables that are readable by the current user.","columns":[{"name":"starelid","type":"oid","description":"The table or index that the described column belongs to","references":"pg_class.oid","hidden":false,"type_oid":26,"attnum":1,"type_modifier":-1,"array_dimensions":0,"not_null":true},{"name":"staattnum","type":"smallint","description":"The number of the described column","references":"pg_attribute.attnum","documented_type":"int2","hidden":false,"type_oid":21,"attnum":2,"type_modifier":-1,"array_dimensions":0,"not_null":true},{"name":"stainherit","type":"boolean","description":"If true, the stats include values from child tables, not just the values in the specified relation","documented_type":"bool","hidden":false,"type_oid":16,"attnum":3,"type_modifier":-1,"array_dimensions":0,"not_null":true},{"name":"stanullfrac","type":"real","description":"The fraction of the column's entries that are null","documented_type":"float4","hidden":false,"type_oid":700,"attnum":4,"type_modifier":-1,"array_dimensions":0,"not_null":true},{"name":"stawidth","type":"integer","description":"The average stored width, in bytes, of nonnull entries","documented_type":"int4","hidden":false,"type_oid":23,"attnum":5,"type_modifier":-1,"array_dimensions":0,"not_null":true},{"name":"stadistinct","type":"real","description":"The number of distinct nonnull data values in the column.
