Simple.

Open a new text file:

,----[  store this as table_copy.sql  ]
| create or replace function table_copy() returns void as $$
| delete from operative.PECDT00;
| insert into operativo.PECDT00 select * from autore.PECDT00;
| $$ language sql;
`----

Now call psql with your Database.

,----[  log from psql  ]
| test=>\i table_copy.sql
| CREATE FUNCTION
|
| test=> select table_copy();
|  table_copy
| ------------
|
| (1 Zeile)
`----


I say it again: use the fine command line tool psql to learn SQL.
