This commit moves authn_id into a new global structure called ClientConnectionInfo (mapping to a MyClientConnectionInfo for each backend) which is intended to hold all the client information that should be shared between the backend and any of its parallel workers, access for extensions and triggers being the primary use case. There is no need to push all the data of Port to the workers, and authn_id is quite a generic concept so using a separate structure provides the best balance (the name of the structure has been suggested by Robert Haas). While on it, and per discussion as this would be useful for a potential SYSTEM_USER that can be accessed through parallel workers, a second field is added for the authentication method, copied directly from Port. ClientConnectionInfo is serialized and restored using a new parallel key and a structure tracks the length of the authn_id, making the addition of more fields straight-forward.

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/.
