Intellisoft OLE DB Provider for PostgreSQL, Server Edition

Intellisoft OLE DB Provider for PostgreSQL, Server Edition

The PGNP provider is a thin layer between Microsoft ADO and PostgreSQL database. It implements most of the OLEDB interfaces and uses libpq to access a PostgreSQL database. The provider can be used from 32-bit and 64-bit applications both native and .NET.

 

Main features are:

•Database conversion with DTS Wizard (MSSQL 2000) or SSIS Wizard (MSSQL 2005/2008/2012).

•Support for SSRS, SSAS and SSIS.

•SQL Server Linked Servers and Replication support.

•Error reporting and execution tracing.

•Transactions support: standard OLEDB, and "nested" PostgreSQL transaction using savepoints.

•Distributed transactions (two phase commit protocol).

•Schema support for tables, views, provider types, columns, primary/foreign keys, indexes, etc.

•Multiple results support.

•Command cancel, prepare and column information on a prepared command.

•Unicode (UTF8) and various languages support.

•Support for PostgreSQL syntax with POSIX and other extensions.

•Partial support for T-SQL statements syntax.

•Internal stored procedures.

•Extended syntax for parameters ('@', ':' and '?') and support for IN, OUT and INOUT parameters.

What's New in 1.4?
The new major version of the PGNP OLEDB Provider for PostgreSQL has several new features and improvements:

  1. Optimizations for very large data sets (1 billion rows and more).
  2. Deferred updates support (IRowsetUpdate).
  3. Better support for Greenplum 4.x (awareness about distribution policy, better use of cursors, gpload utilization for bulk operations, etc.)
  4. Better support for PostgreSQL 9.x.
  5. New utility for Automated updates (not included in the trial build).
  6. Better integration with SSIS (MS BI tools).

The provider is available in two editions: for Desktops (DE)/for Servers (SE). Following table summarizes differences:

 

Postgres DE

Intended for use from desktop applications connecting to Postgres databases only. Some functions would not work with Greenplum, e.g. scrollable cursors, deferred updates, etc.

Postgres SE

Intended for use from servers (IIS, SSAS, SSIS, linked servers, etc.) connecting to Postgres databases only. Optimized for extremely large rowsets, supports two phase commit protocol (DTC enlistment), and provides better integration with SSIS.

Server Edition (SE) has all the features of Desktop Edition (DE), and adds more features as shown in the table above.
