PGNP OLEDB Provider for PostgreSQL, Greenplum and Redshift

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.

    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.

PGNP Project History

Fixed bug in determining types of expressions using now() function and count(bigint).
Fixed crash when getting index schema on very long names.
Fixed bug: CTE can use full SELECT, e.g. WITH... (SELECT ... ORDER BY 1) ...
Fixed bug: unnecessary 'AS' was inserted into query, e.g. SELECT * FROM crosstab('...', '...') AS tbl(...). Result: AS tbl AS.
Fixed bug: column information was returned in lower case, e.g. SELECT 1 as "My Test" from tbl.
Fixed casing bug in output column, e.g. SELECT date_part(...) was returning column name as DATE_PART.
Improved parameters and return types handling for stored procedure.
