pg_stat_xact_all_tables.n_tup_newpage_upd

Description

Source-defined field pg_stat_xact_all_tables.n_tup_newpage_upd. The same-version manual describes this view but does not enumerate this column; the exact SQL expression is retained below.

View

pg_stat_xact_all_tables

Field

n_tup_newpage_upd

Field evidence

Source declaration; not individually enumerated by the manual

Expression declared in

pg_stat_xact_all_tables

Usage

SELECT n_tup_newpage_upd FROM pg_catalog.pg_stat_xact_all_tables;

View semantics

Similar to pg_stat_all_tables, but counts actions taken so far within the current transaction (which are not yet included in pg_stat_all_tables and related views). The columns for numbers of live and dead rows and vacuum and analyze actions are not present in this view.

Collection and transaction context

A transaction can also see its own statistics (not yet flushed out to the shared memory statistics) in the views pg_stat_xact_all_tables , pg_stat_xact_sys_tables , pg_stat_xact_user_tables , and pg_stat_xact_user_functions . These numbers do not act as stated above; instead they update continuously throughout the transaction.

Exact source expression

No per-field definition, effective SQL type, unit, or reset rule is inferred from this expression.

pg_stat_get_xact_tuples_newpage_updated(C.oid)
