I do not understand this question. If you want case sensitivity, you need
to quote your identifiers. Unquoted identifiers are case insensitive.
I do not think the standard states what should happen when you start mixing
quoted and unquoted identifiers for the same object.

No. PostgreSQL stores them in all lower case (Informix also).

The unquoted identifier is converted to all lower case, no flag.
The quoted identifier is taken as is.

Actually, it does:
13)A <regular identifier> and a <delimited identifier> are equiva-
lent if the <identifier body> of the <regular identifier> (with
every letter that is a lower-case letter replaced by the equiva-
lent upper-case letter or letters) and the <delimited identifier
body> of the <delimited identifier> (with all occurrences of
<quote> replaced by <quote symbol> and all occurrences of <dou-
blequote symbol> replaced by <double quote>), considered as
the repetition of a <character string literal> that specifies a
<character set specification> of SQL_TEXT and an implementation-
defined collation that is sensitive to case, compare equally
according to the comparison rules in Subclause 8.2, "<comparison
predicate>".
The spec expects unquoted identifiers to be made case-insensitive by
folding them to upper case. We do it by folding to lower case, instead.
While this isn't 100% standard, it's unlikely to be changed. Too many
applications would break...

OK, lets assume I want the field test explicitly in lowercase (and ONLY in
lowercase). I can see no way to make this with the current implementation.
By the way in Oracle, we have the same problem, but everything is in
uppercase.

This is only set when TAS is defined, so we can just check whether
TAS is defined directly instead.
