By simple, I mean Unless someone else is working on this code, it was done by you. Pretty sure it had to do with from this message: https://www.postgresql.org/message-id/SJ2PR22MB4328CEB1B47FC1AC4A996CB3BAD12%40SJ2PR22MB4328.namprd22.prod.outlook.com "Although I did not explicitly use Postgres to declare inheritance, logically speaking table dataset and processing _node inherit or are subclasses of node because they are subclasses of node in a dataflow diagram." I'm guessing you actually did do the subclassing(inheritance) as it was an option presented in the pgAdmin4 CREATE TABLE screen. Anyway at this point the problem has been identified and a solution devised. > that I used fewer columns in the test version, like so: > > > > Where *node_id* is a foreign key in dataset, and *node_type* is not. > > Best regards, > Mark Brady -- Adrian Klaver adrian.klaver@xxxxxxxxxxx |
