pgtypeslib_extern.h contained fallback definitions of "bool", "FALSE", and "TRUE". The latter two are just plain unused, and have been for awhile. The former came into play only if there wasn't a macro definition of "bool", which is true only if we aren't using <stdbool.h>. However, it then defined bool as "char"; since commit d26a810eb that conflicts with c.h's desire to use "unsigned char". We'd missed seeing any bad effects of that due to accidental header inclusion order choices, but dddf4cdc3 exposed that it was problematic. To fix, let's just get rid of these definitions. They should not be needed because everyplace in Postgres should be relying on c.h to provide a definition for type bool. (Note that despite its name, pgtypeslib_extern.h isn't exposed to any outside code; we don't install it.) This doesn't fully resolve the issue, because ecpglib.h is doing similar things, but that seems to require more thought to fix. Back-patch to v12 where d26a810eb came in, to forestall any unpleasant surprises from future back-patched bug fixes.

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/.
