Prevent logical replication workers from performing insert, update, delete, truncate, or copy commands on tables unless the subscription owner has permission to do so. Prevent subscription owners from circumventing row-level security by forbidding replication into tables with row-level security policies which the subscription owner is subject to, without regard to whether the policy would ordinarily allow the INSERT, UPDATE, DELETE or TRUNCATE which is being replicated. This seems sufficient for now, as superusers, roles with bypassrls, and target table owners should still be able to replicate despite RLS policies. We can revisit the question of applying row-level security policies on a per-row basis if this restriction proves too severe in practice.

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.
