Description

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

Source declaration; not individually enumerated by the manual

Expression declared in

pg_stat_xact_user_functions

Usage

SELECT calls FROM pg_catalog.pg_stat_xact_user_functions;

View semantics

Similar to pg_stat_user_functions, but counts only calls during the current transaction (which are not yet included in pg_stat_user_functions).

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_function_calls(P.oid)
