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. 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/.

Given syntactically wrong input, widget_in() could call atof() with an indeterminate pointer argument, typically leading to a crash; or if it didn't do that, it might return a NULL pointer, which again would lead to a crash since old-style C functions aren't supposed to do things that way. Fix that by correcting the off-by-one syntax test and throwing a proper error rather than just returning NULL. Also, since widget_in and widget_out have been marked STRICT for a long time, their tests for null inputs are just dead code; remove 'em. In the oldest branches, also improve widget_out to use snprintf not sprintf, just to be sure. In passing, get rid of a long-since-useless sprintf into a local buffer that nothing further is done with, and make some other minor coding style cleanups. In the intended regression-testing usage of these functions, none of this is very significant; but if the regression test database were left around in a production installation, these bugs could amount to a minor security hazard.
