named "abc" or "abc  " may be different. so sql should not mix it up. of
course, one might escape every " ", but this would be a workaround, not
a solution.

In that case you should use a type that does not trim trailing spaces.
Maybe you'd like to use a type that's case sensitive as well.

Anyway, a change like this would certainly have to be done upstream.
