When there is a declare content, the subType attribute of the temporary table is lost. (greenplum)

[wfh010624]

When the sql is as follows：

begin
 drop table if exists temp_goods;
    create temp table temp_goods as
    select
        substring(md5(g.gid::varchar),9,16) id,
        g.gid,g.code,g.code2,g."name",g.shortname,g.ename eng_name,
        g.eshortname eng_shortname,g.spec,g.munit qpc_unit,
        g.qpc,g.qpcstr qpc_desc,g.vol,g.tm trademark,g.brand
    from goods g;
end;

the response is:

data.sqlflow.dbobjs.servers[0].databases[0].schemas[0].tables[1]={
        displayName: "temp_goods",
	id: "4",
	name: "temp_goods",
	subType: "temp_table",
	type: "table"
}

When the sql is as follows：

declare 
    v_time date := current_date;
begin
 drop table if exists temp_goods;
    create temp table temp_goods as
    select
        substring(md5(g.gid::varchar),9,16) id,
        g.gid,g.code,g.code2,g."name",g.shortname,g.ename eng_name,
        g.eshortname eng_shortname,g.spec,g.munit qpc_unit,
        g.qpc,g.qpcstr qpc_desc,g.vol,g.tm trademark,g.brand
    from goods g;
end;

the response is:

data.sqlflow.dbobjs.servers[0].databases[0].schemas[0].tables[1]={
        displayName: "temp_goods",
	id: "4",
	name: "temp_goods",
	type: "table",
}

I need the subType attribute to determine whether the table is temporary
