TRIM only trims spaces by default, not all whitespace

[ethan-oro]

TRIM, LTRIM and RTRIM do not trim non-space whitespace if set_of_characters_to_remove is not specified. the following test case with a tab character demonstrates this

{
	name:         "trim",
	query:        `SELECT TRIM('		apple	')`,
	expectedRows: [][]interface{}{{"apple"}},
}

returns

    query_test.go:6075: [0]: (-want +got):
          []any{
        - 	string("apple"),
        + 	string(`		apple	`),
          }
