Thomas Munro 01b55203ac Fix illegal attribute propagation in LLVM JIT. 
Commit 72559438 started copying more attributes from AttributeTemplate
to the functions we generate on the fly.  In the case of deform
functions, which return void, this meant that "noundef", from
AttributeTemplate's return value (a Datum) was copied to a void type.
Older LLVM releases were OK with that, but LLVM 18 crashes.

Update our llvm_copy_attributes() function to skip copying the attribute
for the return value, if the target function returns void.

Thanks to Dmitry Dolgov for help chasing this down.

Back-patch to all supported releases, like 72559438.

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/.
