<sys/uio.h> is in SUSv2, and all targeted Unix system have it, so we might as well drop the probe (in fact we never really needed this one). It's where struct iovec is defined, and as a common extension, it's also where non-standard preadv() and pwritev() are declared on systems that have them. We should also be able to assume that IOV_MAX is defined on Unix. To spell out what our pg_iovec.h header does for the OSes in the build farm as of today: Windows: our own struct and functions Solaris, Cygwin: <sys/uio.h>'s struct, our own functions Every other Unix: <sys/uio.h>'s struct and functions Reviewed-by: Tom Lane <tgl@sss.pgh.pa.us> Discussion: https://postgr.es/m/CA%2BhUKG%2BL_3brvh%3D8e0BW_VfX9h7MtwgN%3DnFHP5o7X2oZucY9dg%40mail.gmail.com |

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
