Hi

three days now. Can anyone help?

Hello,
I have the following two tables
 create table protein
 (structures setof pdb);

 create table pdb
 (identifier text);

That is, I express the fact that a protein has many pdb's as a nested
relation. I then try to insert values into a protein

 insert into protein values (pdb('..'),pdb('..'));

but it does not work. How can I insert values?
 Does Postgres support this feature?

Thanks
Kostas Vassiliadis

NB I also tried
    create table temp
    (numbers setof int);

and tried to insert but couldn't.
