Обсуждение: psqlODBC 08.01.0100 Released
After a long development period, I'm pleased to announce the release of version 08.01.0100 of psqlODBC, the PostgreSQL ODBC Driver. This release represents a major change to the driver over previous versions; in particular, the network code has been replaced with the PostgreSQL libpq library. This allows us to more easily take advantage of updates and new features that might be introduced to the PostgreSQL wire protocol, and also allowed us to upgrade straight away to the version 3 protocol which was previously unsupported. We were also able to add SSL support, as well as Kerberos authentication support. From this release, two versions of the driver are provided for Windows, 'PostgreSQL ANSI' which supports single and multibyte applications through the ANSI ODBC API, and 'PostgreSQL Unicode' which provides Unicode support through the Unicode ODBC API. On Unix systems, the driver type may be selected via a configure option. psqlODBC may be downloaded from http://www.postgresql.org/ftp/odbc/versions/ in source, Windows Installer, merge module, and basic zip file formats. Please post any bug reports to the pgsql-odbc@postgresql.org mailing list. I'd like to take this opportunity to thank all those involved with the development, testing and bug fixing of the updated driver. Dave Page PostgreSQL Core Team

I thought the idea was to have both sets of functions in one binary and let the driver manager or application program figure out which to call. -- Peter Eisentraut http://developer.postgresql.org/~petere/

The Unicode driver will only work with Unicode data or non-unicode data that maps directly into the first unicode page (or whatever the correct term is). Non-ASCII charsets don't work correctly with the Unicode driver as a result. Drivers such as the Microsoft SQL Server driver handle this by having an option to map strings on the fly from the client encoding into unicode. It has to be done this way because if the Unicode functions exist, the driver manager will *always* map all function calls to those instead of the ANSI versions. To get around this without providing our own remapping of non-unicode data, the driver was reverted back to the way it was in the 07.xx series - ie. Having a Unicode and ANSI version on Windows. On Unix, the --enable/disable-unicode option that you added some time back was reinstated. The net result of this change was that a whole heap of complaints from people using latin* as their client encoding went away overnight. I've made no secret of the fact that I know little of encoding issues however, so if you have a better way to handle this then please speak up! Regards, Dave
