According to this:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms711818%28v=vs.85%29.aspx,
both behaviors are permitted. When the driver returns SQL_PARC_BATCH,
when you call SQLGetInfo(conn, SQL_PARAM_ARRAY_ROW_COUNTS, ... ), the
driver returns a separate row count for each parameter (PostgreSQL).
When it returns SQL_PARC_NO_BATCH, it returns a single row count that's
the sum of all parameters (MSSQL). In a portable application, you need
to call SQLGetInfo, and deal with both behaviors.
