Summary

has_largeobject_privilege is a PostgreSQL built-in function in the Miscellaneous Functions group. PostgreSQL’s system catalog (pg_proc) describes it as: “user privilege on large object by username, large object oid”.

Signature

has_largeobject_privilege has 3 documented overloaded forms:

has_largeobject_privilege(name, oid, text) → boolean
has_largeobject_privilege(oid, text) → boolean
has_largeobject_privilege(oid, oid, 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.)
