Removing this code from pg_regress.c makes also sense to me.  Now, the
patch breaks "vcregress installcheck" as this is missing to patch
installcheck_internal() for the tablespace path creation.  I would
also recommend using a full path for the directory location to avoid
any potential issues if this code is refactored or moved around, the
patch now relying on the current path used.
