    • Field Detail

      • PUBLIC

        public static final Lexicals.Identifier.Pseudo PUBLIC
        Instance intended to represent PUBLIC when used as a privilege grantee.

        It would not be correct to use this instance for other special things that happen to be named PUBLIC, such as the PUBLIC schema. That is a real catalog object that has the actual name PUBLIC, and should be represented as a Simple with that name.

        Note: through PG 14 at least, the database itself does not treat the public grantee in the way anticipated here; it is, instead, treated as an ordinary folding name "public" and forbidden as the name of any role. Therefore, a model of grantee roles would not need this symbol after all, but the definition will remain here illustrating the concept.
