PostgreSQLThe 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.
* Wide range of Postgres-compatible databases are supported, i.e. Amazon RDB, Heroku, Yellowbrick, etc.

 

    Main features are:

  • Database conversion with DTS Wizard (MSSQL 2000) or SSIS Wizard (SQL Server 2005/2008/2012/2016/2017/2019).
  • Support for SSRS, SSAS and SSIS (SQL Server 2005/2008/2012/2016/2017/2019).
  • 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.
