Thread: pgsql: Make sure IOV_MAX is defined.
Make sure IOV_MAX is defined. We stopped defining IOV_MAX on non-Windows systems in 75357ab94, on the assumption that every non-Windows system defines it in <limits.h> as required by X/Open. GNU Hurd, however, doesn't follow that standard either. Put back the old logic to assume 16 if it's not defined.
