In p_isdigit and other character class test functions generated by the p_iswhat macro, the code path for non-C locales with multibyte encodings contained a bogus pointer cast that would accidentally fail to malfunction if types wchar_t and wint_t have the same width. Apparently that is true on most platforms, but not on recent Cygwin releases. Remove the cast, as it seems completely unnecessary (I think it arose from a false analogy to the need to cast to unsigned char when dealing with the <ctype.h> functions). Per bug #8970 from Marco Atzeri. In the same functions, the code path for C locale with a multibyte encoding simply ANDed each wide character with 0xFF before passing it to the corresponding <ctype.h> function. This could result in false positive answers for some non-ASCII characters, so use a range test instead. Noted by me while investigating Marco's complaint. Also, remove some useless though not actually buggy maskings and casts in the hand-coded p_isalnum and p_isalpha functions, which evidently got tested a bit more carefully than the macro-generated functions. |

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/.
