Traditionally, SIGUSR1 has been overloaded for ad-hoc signals, procsignal.c signals and latch.c wakeups. Move that last use over to a new dedicated signal. SIGURG is normally used to report out-of-band socket data, but PostgreSQL doesn't use that facility. The signal handler is now installed in all postmaster children by InitializeLatchSupport(). Those wishing to disconnect from it should call ShutdownLatchSupport(). Future patches will use this separation of signals to avoid the need for a signal handler on some operating systems.

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/.
