This patch fixes several related cases in which pg_shdepend entries were never made, or were lost, for references to roles appearing in the ACLs of schemas and/or types. While that did no immediate harm, if a referenced role were later dropped, the drop would be allowed and would leave a dangling reference in the object's ACL. That still wasn't a big problem for normal database usage, but it would cause obscure failures in subsequent dump/reload or pg_upgrade attempts, taking the form of attempts to grant privileges to all-numeric role names. (I think I've seen field reports matching that symptom, but can't find any right now.) Several cases are fixed here: 1. ALTER DOMAIN SET/DROP DEFAULT would lose the dependencies for any existing ACL entries for the domain. This case is ancient, dating back as far as we've had pg_shdepend tracking at all. 2. If a default type privilege applies, CREATE TYPE recorded the ACL properly but forgot to install dependency entries for it. This dates to the addition of default privileges for types in 9.2. 3. If a default schema privilege applies, CREATE SCHEMA recorded the ACL properly but forgot to install dependency entries for it. This dates to the addition of default privileges for schemas in v10 (commit |

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/.
