Currently postgres_fdw doesn't permit a non-superuser to connect to a foreign server without specifying a password, or to use an authentication mechanism that doesn't use the password. This is to avoid using the settings and identity of the user running Postgres. However, this doesn't make sense for all authentication methods. We therefore allow a superuser to set "password_required 'false'" for user mappings for the postgres_fdw. The superuser must ensure that the foreign server won't try to rely solely on the server identity (e.g. trust, peer, ident) or use an authentication mechanism that relies on the password settings (e.g. md5, scram-sha-256). This feature is a prelude to better support for sslcert and sslkey settings in user mappings. Author: Craig Ringer.

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/.
