Lets's say there were already 1000 records in the customers table.
Now I add 357 new customers to this table.
If I use one of your queries I'd get all 1357 entries of customers
since "project_x.projectinfos" would be newly created for this project
and therefor empty.
I need to know which customers.id was created for which line in the
temporary table that I read in with copy.
When I have those ids I can fill "project_x.projectinfos" with just
those new 357 customer.ids and foreign keys refering the new
lookup-tables.
Sorry, I do not understand exactly. What is the difference between the new
357 customers and the existent 1000 customers? If it is the date they
inserted, then the should be filtered by the date. If it is another
attribute like project they are related, then they should be filtered by
the project column or the relation table.
