How correctly to convert datetime to timestamp

I have tried to use OLEDB connection (trial version for Greenplum) in SSIS package for copying table (MS SQL to Greenplum) operation, but I got error: "PostgreSQL Native Provider" Hresult: 0x80004005 Description: "ERROR: insufficient data left in message".
It is a big table not only because rows but columns (almost 100 columns). With good working varchar(s) and int(s) there are a lot of datetime(s) in source. Is it a problem? What can suggestions be made for this error?

It is important that GPLOAD option was used.

Could you send the SQL Server and Postgres tables DDLs to help us reproduce the issue? The DDLs can be e-mailed to support at pgoledb.com. Thank you!
