June 13, 2015 Ver 184.108.40.20662
Fixed bug when preparing query from a function with parameter(s). Previously "function not found" error was returned because parameters types were not passed correctly in the Prepare call.
Added ability to convert procedure parameters to the required type. For example, a stored procedure has parameter of type "timestamp", but the ADO/OLEDB parameter is "string". The PGNP provider will automatically convert the parameter to "timestamp".
Fixed bug in handling command parameters when their ordinal positions are not sequential.
Fixed bug in handling CASE clause: "order of WHEN items was reversed".
Fixed bug in handling of very large numeric values when reading from Postgres DB (47317.234320284904539357876164946677632000).

Added support for time with precision (DBTIME2). Introduced new connection string parameter USE_TIME2=ON/OFF. By default, the parameter is set to ON (enables time with precision). When USE_TIME2=OFF, legacy ADO time type is used (no second fractions allowed). The time with precision is working similarly for Postgres time and timetz types.
Denodo: changed FETCH command to resolve "syntax error"; fixed bugs in determining some field types.
Denodo: altered syntax for declare cursor/fetch; turned events off by default; eliminated transaction start for cursor commands; fixed SCHEMA_CATALOGS.
