The following bug has been logged on the website:
Bug reference: 14521
Logged by: Krzysztof Heim
Email address: krzysztof.heim@gmail.com
PostgreSQL version: 9.6.1
Operating system: Ubuntu 16.04
Description:
Hello,
I have base table A with column type integer array.
I also have table B derived from table A.
When I query pg_attribute for table A, attndims shows 1 (correct), when I do
same query for table B - attndims shows 0 for same column.
Is it a bug, or it's desired behavior (since it's a derived column).
I checked documentation, and it does not say anything about behavior in case
of derived - just says if attndims is > 0 you can assume it's array.
Thanks
