Magnus Hagander 5ee180a394 Add pg_strong_random_init function to initialize random number generator
Currently only OpenSSL requires this initialization, but in the future
other SSL implementations are likely to need it as well. Abstracting
this functionality out into a separate function makes this cleaner and
more clear, and also removes the dependency on OpenSSL headers from
fork_process.c.

OpenSSL is special in that we need to initialize this random number
generator even if we're not going to use it directly, until we drop
support for everything prior to OpenSSL 1.1.1. (And of course also if we
actually use it). All other implementations are left empty at this time,
but more are expected to be added in the future.

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/.
