Thread: pgsql: Move pg_pwritev_with_retry() to src/common/file_utils.c
Move pg_pwritev_with_retry() to src/common/file_utils.c This commit moves pg_pwritev_with_retry(), a convenience wrapper of pg_writev() able to handle partial writes, to common/file_utils.c so that the frontend code is able to use it. A first use-case targetted for this routine is pg_basebackup and pg_receivewal, for the zero-padding of a newly-initialized WAL segment. This is used currently in the backend when the GUC wal_init_zero is enabled (default).
