Could you please provide more details about the problem?
What are the versions of your PostgreSQL server and Devart dotConnect for PostgreSQL?
If possible, please send us (support@devart.com, subject "PostgreSQL unexpected server response") a small test project or at least a piece of code illustrating the problem.
Also, include the script of the DB objects and the connection string.
One more thing: call stack you have provided seems to be incomplete. If possible, post the call stack of the inner exception, if it is present.

I cannot provide you sample code because I have no way of replicating it. It's random and in many different parts of our codebase. What I want to know is what this error message means.
