Summary

pg_stat_reset is a PostgreSQL built-in function in the System Administration Functions group. PostgreSQL’s system catalog (pg_proc) describes it as: “statistics: reset collected statistics for current database”.

Signature

pg_stat_reset() → void

Argument and return types are taken from the pg_proc catalog; internal type names are shown using their readable SQL spellings (for example int4 is shown as integer). (Derived from the catalog — see the linked reference for the canonical documentation.)

Classification

  • Category: System Administration Functions
  • Kind: Function
  • Volatility: VOLATILE — Marked VOLATILE — its result can change even within a single statement (for example, it may depend on time, sequences or the current session).
  • Returns: void

Example

Illustrative form (replace placeholder values with your own data):

SELECT pg_stat_reset();

The example above is illustrative and is meant to show calling syntax only; consult the linked PostgreSQL documentation for exact semantics, edge cases and accepted argument combinations.
