Doing an abort() seems all right in development builds, but not in production builds of general-purpose libraries. However, the functions that were doing this lack any way to report a failure back up to their callers. It seems like we can just get away with ignoring failures in production builds, since (a) no such failures have been reported in the dozen years that the code's been like this, and (b) failure to enforce mutual exclusion during fe-auth.c operations would likely not cause any problems anyway in most cases. (The OpenSSL callbacks that use this macro are obsolete, so even less likely to cause interesting problems.) Possibly a better answer would be to break compatibility of the pgthreadlock_t callback API, but in the absence of field problem reports, it doesn't really seem worth the trouble.

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/.
