I finished up making a few more improvements: 1. I eventually figured out how to generalise compute_remaining_iovec() (as I now call it) so that the existing pg_pwritev_with_retry() in file_utils.c could also use it, so that's now done in a patch of its own. 2. FileReadV/FileWriteV patch: * further simplification of the traditional ENOSPC 'guess' * unconstify() changed to raw cast (pending [1]) * fixed the DO_DB()-wrapped debugging code 3. smgrreadv/smgrwritev patch: * improved ENOSPC handling * improve description of EOF and ENOSPC handling * fixed the sizes reported in dtrace static probes * fixed some words in the docs about that * changed error messages to refer to "blocks %u..%u" 4. smgrprefetch-with-nblocks patch has no change, hasn't drawn any comments hopefully because it is uncontroversial. I'm planning to commit these fairly soon. [1] https://www.postgresql.org/message-id/flat/CA%2BhUKGK3OXFjkOyZiw-DgL2bUqk9by1uGuCnViJX786W%2BfyDSw%40mail.gmail.com
