--------------------------------------------------------------

Brief update on this issue.

Following unparsing errors have been fixed:
 * Calcite cannot unparse RexNode back to bytes literal
 * Calcite cannot unparse some floating point literals correctly
 * Calcite cannot unparse some string literals correctly

Other issues from the initial list (INTERVAL and CAST) still need to be fixed.
