It's supposed to work, and there are regression tests in
src/test/modules/libpq_pipeline/libpq_pipeline.c [1]
that exercise the single row mode and PQpipelineSync().
You might want to compare your code workflow with how it's done in
that file, and maybe submit a bug report with your test case if the
conclusion is that your code should not error out.
