        Note that the maximum length of an identifier is 63 by default, but can

        be changed by recompiling PostgreSQL after editing the NAMEDATALEN

        macro in src/include/pg_config_manual.h .



        This implementation simply returns 63, but can easily be overridden by a

        custom database backend that inherits most of its behavior from this one.
