Andres helped me to produce a correct dump, my error was that the
breakpoint should have been one line earlier because of elog()
internals.

The outcome is that Andres diagnosed it as a bug in mysql_fdw;
ExecInitExpr() should never get toplevel lists anymore.

Bug filed: https://github.com/EnterpriseDB/mysql_fdw/issues/147

Thanks,
Christoph
