Even though our existing code for handling credentials control messages has been basically unchanged since 2001, it was fundamentally wrong: it did not ensure proper alignment of the supplied buffer, and it was calculating buffer sizes and message sizes incorrectly. This led to failures on platforms where alignment padding is relevant, for instance FreeBSD on 64-bit platforms, as seen in a recent Debian bug report passed on by Martin Pitt (http://bugs.debian.org//cgi-bin/bugreport.cgi?bug=612888). Rewrite to do the message-whacking using the macros specified in RFC 2292, following a suggestion from Theo de Raadt in that thread. Tested by me on Debian/kFreeBSD-amd64; since OpenBSD and NetBSD document the identical CMSG API, it should work there too. Back-patch to all supported branches. |

This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: http://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. Changes between all PostgreSQL releases are recorded in the file HISTORY. 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.
