Summary

has_column_privilege is a PostgreSQL built-in function in the Mathematical Functions group. PostgreSQL’s system catalog (pg_proc) describes it as: “user privilege on column by username, rel name, col name”.

Signature

has_column_privilege has 12 documented overloaded forms:

has_column_privilege(name, text, text, text) → boolean
has_column_privilege(name, text, smallint, text) → boolean
has_column_privilege(name, oid, text, text) → boolean
has_column_privilege(name, oid, smallint, text) → boolean
has_column_privilege(oid, text, text, text) → boolean
has_column_privilege(oid, text, smallint, text) → boolean
has_column_privilege(oid, oid, text, text) → boolean
has_column_privilege(oid, oid, smallint, text) → boolean
has_column_privilege(text, text, text) → boolean
has_column_privilege(text, smallint, text) → boolean
has_column_privilege(oid, text, text) → boolean
has_column_privilege(oid, smallint, text) → boolean

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: Mathematical Functions
  • Kind: Function
  • Volatility: STABLE — Marked STABLE — within a single statement it returns a consistent result for the same arguments, but the result can change between statements.
  • Returns: boolean

Example

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

SELECT has_column_privilege('abc', 'abc', 'abc', 'abc');

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

has_column_privilege 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.
