Well, we can file that under "doesn't work".  Did you get no other
message before that one?  Usually a TDS_DONE_ERROR from the server is
preceded by a message, and something like "invalid handle" would occur
later, after the program continues blithely on.  That's "usually" as
in, I've never seen an exception.

Does it help if you "set textsize 10000000" (10 million) first?  The
constraint in your configuration file

might not matter; you said its name is "/etc/freetds/freetds.ini" and
that would normally be /etc/freetds/freetds.conf.
