How best to append a list of tables to an empty table to form a whole table?

Pseudo codes show the desirable logic.



There are a list of tables with exactly same colums
table_a
table_b
table_c

Create an empty table  emp_table

Foreach a_name in ARRAY ARRAY['table_a', 'table_b', 'table_c'] loop
   insert into em_table as select * from table a_name

end loop;

Can something like that be done is PostGIS?

Regards,

David
