According to [Microsoft](https://msdn.microsoft.com/en-us/library/cc704588.aspx), `0xC0000005` represents `STATUS_ACCESS_VIOLATION`. There are some clues about what that might mean [here](https://www.cygwin.com/ml/cygwin/1998-05/msg00663.html). I will try to find time to take a look at this at some...

Nice work, @lorenati! FreeTDS uses iconv to do character set conversions. The version of the FreeTDS protocol that you are using can effect what conversions are used. For example, when...

Weird. It looks like tds_fdw is casting the column to "timestamp without time zone" on the remote server, but this should actually be mapped to "datetime2" on the remote server....

Thanks for linking to mysql_fdw's documentation as an example. I didn't realize that they added where clause push-down and column push-down in a recent release. If I ever decided to...

@oberstet If you don't mind, let's discuss that option via email. Could you please send me an email to [email protected] about this?

I just merged WHERE and column pushdown into master in this commit: https://github.com/GeoffMontee/tds_fdw/commit/d1e8f109e814cc6f982e9ff27fcbe2d967540b19 It is based on a port of deparse.c from postgres_fdw to tds_fdw. It only compiles on PostgreSQL...

The latest commit has this feature working all the way back to 9.2: https://github.com/tds-fdw/tds_fdw/commit/da3c823fdbbe697331cd213bd1cd40f8864c72c4 If anyone tests it out and has any problems, please let me know.

Thanks for the bug report, @decibel! What version of PostgreSQL are you using? With PostgreSQL 9.4 or later, tds_fdw should use `make_timestamp()`, rather than trying to do a string conversion,...

A NULL timestamp seems to work for me on PostgreSQL 9.5. I created a test table on the MS SQL Server: ``` CREATE TABLE dbo.null_datetime ( id int primary key,...
