Which we know is incorrect. We should instead make it uppercase, but
that would break compatibility with older version (SQL 92 draft, 5.2 SR10)
>create table "Table" ( id int );
>select * from Table;
>You get "relation table not found".
That seems to me to be the correct results given 5.2 SR 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>"."
I believe that it would require the identifiers in the following to
be the same, whereas PostgreSQL would treat them as different.
create table "TABLE"(id int);
select * from Table;
