find_composite_type_dependencies correctly found columns that are of the specified type, and columns that are of arrays of that type, but not columns that are domains or ranges over the given type, its array type, etc. The most general way to handle this seems to be to assume that any type that is directly dependent on the specified type can be treated as a container type, and processed recursively (allowing us to handle nested cases such as ranges over domains over arrays ...). Since a type's array type already has such a dependency, we can drop the existing special case for the array type. The very similar logic in get_rels_with_domain was likewise a few bricks shy of a load, as it supposed that a directly dependent type could *only* be a sub-domain. This is already wrong for ranges over domains, and it'll someday be wrong for arrays over domains. Add test cases illustrating the problems, and back-patch to all supported branches.

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
