In case of parallel INSERT (max_insert_threads > 1) it is possible for VIEW to be DROP/DETACH'ed while building pipeline for various paralell streams, and in this case the header will not match since when you have VIEW you will got empty header and non-empty header otherwise. And this leads to LOGICAL_ERROR later, while checking that output headers are the same (in QueryPipelineBuilder::addChains() -> Pipe::addChains()). However it also makes the pipeline different for various parallel streams, and it looks like it is better to fail in this case, so instead of always returning empty header from buildChainImpl() explicit check had been added. Note, that I wasn't able to reproduce the issue with the added test, but CI may have more "luck" (although I've verified it manually).
