My point was just that "valid" seems redundant. (Sorry, but..)
However, looking again, many of the "cases" are like "requires a
<type> value", which looks womewhat similar to "requires a valid
value" when the <type> cannot be represented by a word. Some remaining
example of these "caes" are:
./commands/define.cÀ54: errmsg("%s requires a
parameter",
(the "parameter" means the option value for type name)
./libpq/hba.cÀ1319: errmsg("authentication method
\"%s\" requires argument \"%s\" to be set", \
But, since I'm not a native speaker, so I don't stress this further
more.

Thanks for the opinion! I agree to you.
Thanks!
