-- @testpoint: opengauss关键字enum(非保留)，作为函数名，部分测试点合理报错

--关键字不带引号-成功
drop function if exists enum;
create function enum(i integer)
returns integer
as $$
begin
    return i+1;
end;
$$ language plpgsql;

drop function if exists enum;
--关键字带双引号-成功
drop function if exists "enum";
create function "enum"(i integer)
returns integer
as $$
begin
    return i+1;

drop function if exists "enum";
--关键字带单引号-合理报错
drop function if exists 'enum';
create function 'enum'(i integer)
