Hello,
I'm not sure to understand well your problems but it seems you have sql
questions rather than postgis ones... For the first one, I don't really
understand what you are looking for but I think what you want to add is
constraint called foreign key (you will find useful information in
For the second part,
it depends hugely on how you edit the field.
Are you editing with psql, pgadmin, qgis, ...

Maybe you already have some values in the code column of VTA which do
not exist in the code column of the survey table? You can not create a
constraint when existing data already violate the constraint.
No, the table VTA is totally empty.
