--创建一个模式schema_for_label
postgres=# CREATE SCHEMA schema_for_label;

--创建一个视图view_for_label
postgres=# CREATE VIEW view_for_label AS SELECT 1;

--创建一个函数func_for_label
postgres=# CREATE FUNCTION func_for_label RETURNS TEXT AS $$ SELECT col1 FROM tb_for_label; $$ LANGUAGE SQL;

--基于表创建资源标签
postgres=# CREATE RESOURCE LABEL IF NOT EXISTS table_label add TABLE(public.tb_for_label);

--基于列创建资源标签
postgres=# CREATE RESOURCE LABEL IF NOT EXISTS column_label add COLUMN(public.tb_for_label.col1);

--基于模式创建资源标签
postgres=# CREATE RESOURCE LABEL IF NOT EXISTS schema_label add SCHEMA(schema_for_label);

--基于视图创建资源标签
postgres=# CREATE RESOURCE LABEL IF NOT EXISTS view_label add VIEW(view_for_label);

--基于函数创建资源标签
postgres=# CREATE RESOURCE LABEL IF NOT EXISTS func_label add FUNCTION(func_for_label);
