My initial impression that glibc was measuring the precision in characters (which is what the Linux man page says it does) was incorrect. It does take the precision to be in bytes, but it also tries to truncate the string at a character boundary. The bottom line remains the same: it will mess up if the string is not in the encoding it expects, so we need to avoid %.*s anytime there's a significant risk of that. Previous code changes are still good, but adjust the comments to reflect this knowledge. Per research by Hernan Gonzalez. |

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: 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. The latest version of this software may be obtained at http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
