Hello all According to https://www.postgresql.org/docs/current/sql-syntax-lexical.html, "Key words and unquoted identifiers are case insensitive." And "SQL identifiers and key words must begin with a letter (a-z, but also letters with diacritical marks and non-Latin letters) or an underscore (_). Subsequent characters in an identifier or key word can be letters, underscores, digits (0-9), or dollar signs ($)." So far so good. Non-latin letters are included, which I take to also include the danish letters æøå/ÆØÅ. However, name-folding is odd for these letters. Of these three create tables, the two first succeed, the last one does not (G and g is equivalent, Æ and æ is not). create table æblegrød (a int, køn text); create table ÆblegrØd (a int, køn text); create table ÆbleGrØd (a int, køn text); Can anyone explain the logic that rules this.
