Do you need the columns from both tables in one single column? Then you
have to join this tables, i don't know how you want to join this tables.
What i meant was:
you can use this:
for i in select * from "Table1" union all select * from "Table2" loop
-- do something
end loop;
within a pl/pgsql-function.
