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!
