Hi
Regards

When I learned to use pg_statsinfo, I typed the following command and got an error:

$ pg_statsinfo a b c d
ERROR: too many argumetns

I noticed a spelling mistake in this error message,
"argumetns" shoudle be "arguments".

I made a patch (See the attachments)for it,
and incidentally fixed another spelling mistake in the same file.
