Summary

int4multirange is a PostgreSQL built-in function in the Range Functions group. PostgreSQL’s system catalog (pg_proc) describes it as: “int4multirange constructor”.

Signature

int4multirange has 2 documented overloaded forms:

int4multirange() → int4multirange
int4multirange(int4range) → int4multirange

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: Range Functions
  • Kind: Function
  • Volatility: IMMUTABLE — Marked IMMUTABLE — it always returns the same result for the same arguments and can be used in indexes and other contexts that require immutability.
  • Returns: int4multirange

Example

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

SELECT int4multirange();

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.

Version applicability

int4multirange is present across the surveyed releases (PostgreSQL 15, 16, 17, 18, 19). On older major versions, behaviour may differ in detail — always check the documentation for the version you run.
