3. Features and Capabilities

The pgExpressPostgreSQL dbExpress™ Driver can access PostgreSQL databases, use all its field types, and is complient to the Borland specifications of dbExpress™ drivers. The pgExpress Driver also includes support for stored procedures (emulated through PostgreSQL functions).

The pgExpress Driver is the core of the pgExpress Suite of components, which provides the widest range of support to acessing PostgreSQL databases. Asynchronous connections can't be supported by current Borland's dbExpress™ implementation; arrays are mapped as strings (see Known Issues) and ADT (custom fields) support will be fully supported only by the pgExpress Suite. It has support for all the most commonly used PostgreSQL field types; notably: int2, int4, int8, serial, char, varchar, text, date, datetime, time, timestamp, timestamp with time zone, BLOB (large objects; read only), float, real, numeric and others).
