The LOWER() function is not adding the spaces; the char() datatype is
adding the spaces.  The "char = text" compare operator ignores the
spaces at the end of the char type.  But when you use the lower function
the type is returned as varchar() including the spaces, and the "varchar
= text" operator doesn't ignore the spaces.  Try either changing the
type to varchar which won't add the spaces to the end, or using
"LOWER(TRIM(char)) = text".
