Schema handling within plpgsql

Hello list,

I need to setup some 80 schemas for work.

What is the proper plpgsql syntax for looping through schemas?
(postgresql 7.4.1)

Ideally it would be nice to do something like:

for schema in 1,2,3,4,5
do
create $schema.table ...
insert into $schema.table select ....
done

I know this can be done from a shell and invoke psql each time, just
wondering if it all can be contained inside plpgsql scripts.

Thanks

george
