Please see the documentation (README.tablefunc). You need to properly
specify the column definitions in the FROM clause, i.e. (untested):
SELECT "ID_WINUSER" FROM connectby('"WINUSER"', '"ID_WINUSER"','"REF_ID_WINUSER"', 4, 0, '~') AS t("ID_WINUSER"
integer, "REF_ID_WINUSER" integer, level integer, branch text);
