subscript_obj

Enterprise scalar function reference.

Function Snapshot

Field Value
Function subscript_obj
Category Internal and Engine Compatibility
Scope Scalar expression
Discovery SELECT * FROM pg_catalog.pg_proc WHERE proname = 'subscript_obj';

Purpose

Implements internal expression semantics used by parser and planner; exposed for compatibility.

Syntax

SELECT subscript_obj(...);

Parameters

  • Positional arguments as defined by overload signatures in pg_catalog.pg_proc.

Returns

  • Returns function-specific scalar/array/object according to resolved overload.

Null and Error Behavior

  • Most overloads are deterministic and null-propagating unless documented otherwise.
  • Validate concrete overload behavior with pg_catalog.pg_proc in your running build.

Operational Notes

  • This function/operator form is primarily internal compatibility surface and may change with planner evolution.
  • Validate overload details in-cluster with pg_catalog.pg_proc and pg_get_function_result(oid).
