i wonder which query operation could have produced this error.
In current code base, "Coercion from ... to the signature" seems to be
produced by function-related coecions, but in the query there is no function
call, unless `logs` is a view. In such case, knowing the view definition can be
necessary to reproduce the error.
In any case, here is a proposal to improve the error message:
