[GENERAL] Drop only temporary table

[Durumdara]

Dear PG Masters!

As I experienced I can create normal and temp table with same name.

create table x (kod integer);

CREATE TEMPORARY TABLE x (kod integer);

select tablename from pg_tables where schemaname='public'
 union all
select c.relname from pg_class c
join pg_namespace n on n.oid=c.relnamespace
where
n.nspname like 'pg_temp%'
and c.relkind = 'r'
and pg_table_is_visible(c.oid);

---

I can see two x tables.

As I see that drop table stmt don't have "temporary" suboption to determine
which to need to eliminate - the real or the temporary.

Same thing would happen with other DDL/DML stmts - what is the destination
table - the real or the temporary?

"insert into x(kod) values(1)"

So what do you think about this problem?

I want to avoid to remove any real table on resource closing (= dropping of
temporary table).
How to I force "drop only temporary"? Prefix, option, etc.

Thanks for your help!
