These functions should take a pg_locale_t, not a collation OID, and should call mbstowcs_l/wcstombs_l where available. Where those functions are not available, temporarily select the correct locale with uselocale(). This change removes the bogus assumption that all locales selectable in a given database have the same wide-character conversion method; in particular, the collate.linux.utf8 regression test now passes with LC_CTYPE=C, so long as the database encoding is UTF8. I decided to move the char2wchar/wchar2char functions out of mbutils.c and into pg_locale.c, because they work on wchar_t not pg_wchar_t and thus don't really belong with the mbutils.c functions. Keeping them where they were would have required importing pg_locale_t into pg_wchar.h somehow, which did not seem like a good plan. |

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.
