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 ([email protected], 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.

We cannot identify the problem with the information you have provided.
1. Please post here the full call stack when the error occurs.
2. Is there any inner exception? If yes, please give us its message text, and its call stack.
3. Please specify the versions of your dotConnect for PostgreSQL and PostgreSQL server.
