Hi everyone. I looked online for how to hold an array of elements with each value being a foreign key and found this: https://stackoverflow.com/questions/41054507/postgresql-array-of-elements-that-each-are-a-foreign-key. However, this did not work for me. The comments on the post suggested there will be a patch in postgresql to accomplish this, but if the patch exists, cs1's version of postgresql does not have it. How do you approach storing a list of foreign keys in your postgresql database?
