Support for PostgreSQL's 8.3 UUID fields.

Documentation enhancements.

Enhanced multithreading functionality.

OID fields will always be mapped as int4. Please check OID type for details.

Fixed GetProcedureParams() interface, what fixes store procedures usage under IDE.

Fixed RoleName parameter under protocol 4.0 (Delphi 2007+).

Fixed access violations in some particular situations.

PostgreSQL 8.3 support. XML fields will be mapped the same way TEXT fields are, i.e. as Blob/Memo; Section 4, “Types Mappping” for details.

Enhanced Delphi 2007+ support (dbExpress 4 support). Please see Installation on dbExpress 4.0 protocol (Delphi 2007+) for details. With that feature comes also new DBX4Compatible special param.

Now the pgExpress Driver can generate large log messages (> 1024 bytes) (log messages can be captured by TSQLMonitor instances).

Documentation enhancements.

Documentation enhancements.

Fixed size of GRAPHIC blobs

Preliminar PostgreSQL v8.2 support. Please read the version-specific notes.

Fixed a couple OUT parameters Stored Procedures problems.

Fixed a problem in the GetProcedureParams interface.

Documentation enhancements.

Fixed a bug retrieving Stored Procedure names.

Fixed escaped characters in memo fields.

Fixed include in pgeDriverUtils.pas.

Fixed numeric without precision/scale, such as:

create table test(a numeric));

Support for the EnterpriseDB.

Documentation enhancements.

Fixed a bug on Memo fields with protocol 3.0 drivers (garbage at the end of the field).

Fixed a problem with stored procedure parameters introduced on the 4.x series.

Fixed a problem with empty string parameters under Kylix.

Added a workaorund for a PostgreSQL parser bug where floats are not recognized if not quoted (ex: update mytable where myfloat = 1.00)

Added support for the VCL/CLX "Trim Char" parameter.

Fixed a bug with string parameters on protocol v3.0 drivers.

Fixed a bug on virtual cursor interfaces that could cause problems on the GetColumnNames() interface in and stored procedures.

Added BDS 2006 compatibility. This includes support for protocol v3.0, unicode interfaces, native int64, enhanced dbExpress API. pgExpress is the first driver to add such support.

Enhanced UNICODE support. Check also the UnicodeAsWideChar parameter. If you have problems opening bases with UNICODE encoding, add a client encoding to your dbxconnections(.ini) entry, such as:

ServerCharset = /latin1

For more details, please refer to Section 1, “Multibyte, UNICODE and Locales”.

With the introduction of protocol 3.0 support in BDS 2006, now we have two new drivers, dbexpge30.dll and dbexpge30-ml.dll, whose implement it. These drivers will work only on BDS 2006 and later. The regular pgExpress Driver which implements dbExpress protocol 2.5 still works with BDS 2006, but pgExpress protocol 3.0 won't work with applications built for older protocol implementations.

Added UnicodeAsWideChar special param: will map char/varchar fields as TWideString fields. This will work only if the client encoding is UNICODE, and with protocol 3.0 or above.

Added BorlandCompatible special param, which adds more compatility between pgExpress and Codegear drivers, on the NUMERIC mapping.

Documentation enhancements.

The following new interfaces are supported:

Most of these interfaces will only be recognized on BDS 2006 please check your IDE documentation for more details.

The libpq library was updated to version 8.1.2, for both Linux and Windows.

Now if the client encoding is UNICODE and the application does not support that encoding (all compiled with compilers before BDS 2006), or do not user UnicodeAsWideChar, the pgExpress Driver will automatically set the client encoding to LATIN-1. While it should fit most users, it can be easily changed to any desired encoding value by using the ServerCharset parameter.

Fixed a bug where the ByteaMode Special Param would not be recognized on all situations.

Fixed libpq dependencies on comerr32.dll and other external libraries.

Fixed libpq loading under Win9X.
