Waken related worker processes immediately at commit of a transaction that has performed ALTER SUBSCRIPTION (including the RENAME and OWNER variants). This reduces the response time for such operations. In the real world that might not be worth much, but it shaves several seconds off the runtime for the subscription test suite. In the case of PREPARE, we just throw away this notification state; it doesn't seem worth the work to preserve it. The workers will still react after the eventual COMMIT PREPARED, but not as quickly.

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/.
