This sounds like you want to have a one-to-many relationship between
your record and its associated files. What you need to do is create a
separate table that will reference your record id:
CREATE TABLE associated_files (
fileid serial PRIMARY KEY,
recordid int REFERENCES master_records (id),
filepath text NOT NULL
);
Does that help?
