Oh right.  (Pokes at it...)  It looks like the backend accepts
"FROM STDOUT" as a synonym for "FROM STDIN", so that's why this
is checking for both spellings.  But I agree it'd be better
for the error message to only use the standard spelling.

Also I tried

regression=# copy int4_tbl from program stdin;
ERROR:  STDIN/STDOUT not allowed with PROGRAM

So we probably don't need to bother with adjusting the check
to allow that.
