The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/9.6/ddl-constraints.html Description:
I think the information about the "order of execution" when checking CHECK constraints when inserting or updating records is missing in the documentation. There seems to be an old e-mail thread on the topic, however, there is no information on whether the patch submitted was already merged and if so, in which version of PostgreSQL. I also suggest it would be good to point out in the documentation how the order of CHECK constraints is created when there are more column CHECK constraints and table CHECK constraints (i.e. in mixed cases) or whether only the name of the constraint is relevant when it comes to it, not its type (column/table). Thank you very much in advance. Kindest regards, Ľudovít
