I have a new database with five tables, and text files with data to populate the tables using the insert command. 1. Each table has a sequential primary key. Should I manually add keys to each insert row or will postgres generate it automatically? Example, for the companies table: org_id | integer | | not null | nextval('companies_org_id_seq'::regclass) org_name | character varying(64) | | not null | 2. Should I use sepatate files as input to each table or can I combine them in a single file? For example, adding a company name and contact name for someone in that company using input commands for both tables in a single file? I will need to provide the primary key to the company table as the foreign key in contact table and have not before pupulated multiple related tables in a new database from .sql files. TIA, Rich
