The syntax in sql2003 do allow it. The exact semantics is difficult to
get a clear picture of from the spec (as always).
I thought this question was the whole argument. We can't have something
like the above with the pg overloading since then the resolving process
will be too hard according to Tom.

Shouldn't we just define the charset for user names and database names?
Either one fixed or one that's set during initdb. You don't mean that we
want different user numes to be defined using different charsets?
The rest of the points looks good to me. The main problem is still what to
do with the function definitions as above. Is it something we want or not?
Is the charset something that makes two text types different or not?
