Subject: pgsql: Provide helper for retrying partial vectored I/O.

Message-ID: <E1rCoS8-009kLx-F7@gemulon.postgresql.org> (raw)
Provide helper for retrying partial vectored I/O.
compute_remaining_iovec() is a re-usable routine for retrying after
pg_readv() or pg_writev() reports a short transfer. This will gain new
users in a later commit, but can already replace the open-coded
equivalent code in the existing pg_pwritev_with_retry() function.
